Travel Trailer and Camper Manufacturing (U.S.) — NAICS 336214

An investor's primer. NAICS (North American Industry Classification System) code 336214 covers the factories that build towable recreational vehicles and related trailers — the units that hitch behind a truck or car rather than driving themselves.

1. Overview

This is the business of building towable RVs (recreational vehicles) — travel trailers, fifth-wheels, pop-up/folding campers, teardrops, truck-mounted campers and truck caps — plus ordinary cargo and utility trailers. Towables make up roughly 88% of all RV units sold in the United States, so this code is the heart of the RV manufacturing economy [1][2].

Why an investor should care: it is a concentrated, brand-driven, highly cyclical consumer-durables industry. A handful of factories in one Indiana county build most of the product, and demand swings violently with interest rates and consumer confidence — annual U.S. shipments ran from a record 600,240 units in 2021 down to 313,174 in 2023 and back to ~342,000 in 2025 [2][3][4]. That volatility is the opportunity and the risk.

Ways in differ by investor type. Public-market investors can own the two listed manufacturers (Thor and Winnebago) or, more cleanly, the listed component suppliers (LCI Industries, Patrick Industries) and the largest dealer (Camping World). Private investors mostly cannot buy the biggest builders — the #2 manufacturer, Forest River, is a wholly owned Berkshire Hathaway subsidiary — but can back independent trailer builders, dealerships, campground/RV-park real estate, or the supplier base. Details are in Sections 4 and 10.

2. What it is and how it's structured

In scope (NAICS 336214): establishments primarily building (1) travel trailers and campers designed to be towed by a car or light truck; (2) truck-mounted "pickup coaches" (slide-in campers) and truck caps/covers; and (3) automobile, utility and light-truck trailers (cargo trailers, boat trailers, single-car transporter trailers, non-fifth-wheel horse trailers, etc.) [5][6].

Explicitly excluded — and this matters for reading the numbers:

• Motor homes (the RV drives itself) are NAICS 336213, Motor Home Manufacturing — a separate code [5].
• Manufactured/mobile homes built to permanent-connection housing standards are NAICS 321991 [5].
• Heavy truck trailers are NAICS 336212 [6].
• Self-propelled vehicles and van conversions sit in the broader NAICS 3361 motor-vehicle codes.

So 336214 is towables plus generic trailers, not "all RVs." A travel trailer and a landscaper's utility trailer share this code; a Winnebago motor coach does not. This boundary matters for reading data: "the RV industry," "towable RVs" and NAICS 336214 are not interchangeable. RV shipment reports omit the code's utility, cargo and light-truck trailers, while total-RV statistics add motorhomes that the code excludes. Company RV segments likewise generally cover travel trailers and fifth wheels, not every product classified in 336214. That breadth is why federal receipts for the code run higher than RV-only industry tallies (Section 3).

How it's made. For recreational products, manufacturers buy frames, axles, appliances, windows, furniture, cabinetry, plumbing and electrical systems, then perform relatively short-cycle assembly and finishing. Winnebago says its towables are produced at two Indiana assembly campuses, with frames, appliances and furniture purchased from multiple suppliers; principal raw materials include steel, aluminum, fiberglass and wood products [7]. The factory mostly cuts, fastens and assembles — this is a "stick-and-staple" business, not a heavy-machinery or technology sector.

Ownership mix. The RV portion is dominated by a few large, professionally managed corporate groups that own dozens of brands; the generic-trailer portion is a long tail of small, often family-owned regional welders and fabricators. There is very little venture or startup activity.

3. How big it is

Federal ground-truth figures for NAICS 336214:

Concentration is high. The four largest firms account for 71.4% of receipts, the top eight for 76.4%, and the top twenty for 83% [8]. At the ownership level the concentration is even starker: Patrick Industries estimates that Thor Industries, Forest River and Winnebago together represented approximately 86% of towable retail unit share in 2025 [11]. (The Herfindahl-Hirschman Index, a standard concentration gauge, is suppressed in the federal data for this code [8].)

RV towable shipments by type (2025). RVIA's line-item breakdown shows 232,474 conventional travel trailers, 65,611 fifth wheels, 3,945 folding camping trailers and 4,084 truck campers, totaling 306,114 towable RV units [1]. This is a wholesale unit count for RVs only — it excludes the utility and cargo trailers that share the NAICS code.

Three caveats on the size figures. First, because the code bundles cargo/utility trailers and truck caps with RVs, these totals somewhat overstate the towable-RV slice — RV-only industry sources put 2025 wholesale RV value (all types) near $20.4 billion at retail [2]. Second, the $27.6 billion receipts figure is a 2022 snapshot near the top of the post-pandemic boom; the industry was materially smaller by unit volume in 2023–2025. Third, RVIA's 2025 year-end press release contains minor internal discrepancies (headline totals of 342,220 RVs and 306,191 towables vs. line-item totals of 342,121 and 306,114); the difference is small but unexplained [1]. Unlike sectors dominated by government or by tiny informal operators, this industry is captured well by federal statistics — it is real factories with payrolls — so undercounting is not a serious concern here; the main pitfall is scope (trailers vs. RVs) and timing (which year).

Geographic concentration is extreme. Indiana — specifically the Elkhart County area — builds roughly 86% of all RVs made in the U.S. and Canada [12]. The supplier ecosystem is clustered in the same region, which lowers logistics cost but concentrates operational and labor-market risk.

4. The investable universe

Only two pure RV manufacturers trade publicly; the richer set of listed plays is the supplier and dealer network around them. Tickers and scale below are for context, not recommendations.

Public manufacturers

Largest private / other manufacturer

• Forest River, Inc. — the #2 RV maker and Thor's chief rival, owned by Berkshire Hathaway since 2005; brands include Coachmen, Cherokee, Rockwood, Salem and Wildwood. Berkshire reported Forest River at approximately 36% of the overall RV market in December 2025 [17]. Not separately investable; exposure only via Berkshire (NYSE: BRK.A/BRK.B), and Berkshire does not separately disclose Forest River revenue or profit. Thor and Forest River together control over 80% of the U.S. RV market by units [16][17].

Public suppliers and the largest dealer (often cleaner ways to play the cycle)

Customer concentration note. FreedomRoads — the principal operating business behind Camping World — represented approximately 14% of Thor's fiscal 2025 sales and receivables [13]. Manufacturers also commonly guarantee or repurchase dealer inventory financed by third parties following dealer default, creating contingent exposure beyond ordinary receivables.

The rest of the ~575 firms in the code are small private trailer and camper builders — approachable for private buyers but individually tiny.

5. How the money works

This is a build-to-dealer-order, low-capital, labor-flexible assembly business. The unit economics that matter:

• Volume × ASP (average selling price). Revenue is units shipped times price. Mix drives ASP: fifth-wheels and luxury trailers sell for far more than pop-ups and teardrops, so a shift toward cheaper, lightweight units (as happened in 2024–2025 for affordability) can grow units while shrinking dollars [2][20].
• Bought-in components dominate cost. Aluminum, steel, lumber/plywood (notably imported Indonesian lauan), appliances, axles, tires and resins are purchased; the factory mostly cuts, fastens and assembles. Gross margin is therefore very exposed to input prices and to labor rather than heavy machinery [21].
• Segment margin benchmarks. Thor's North American Towable segment generated $3.785 billion of sales and $497 million of gross profit in fiscal 2025, a 13.1% gross margin; material, labor, outbound freight and warranty together consumed 78.8% of sales. Segment pretax income was approximately 6.5% of sales [13]. Winnebago's Towable RV segment generated $1.22 billion of revenue and $72.7 million of operating income, a 6.0% operating margin, down from 7.8% in fiscal 2024 due to fixed-cost deleverage, lower-priced mix and higher warranty expense [15].
• Low fixed capital, flexible labor. Because assembly is labor-intensive and plants are cheap to idle, builders can flex production up or down fast. That is why margins hold up better than autos in a downturn (they cut build rates hard) but also why the industry over- and under-builds relative to retail demand.
• The wholesale-vs-retail channel is the key tell. Manufacturers book revenue when they ship to dealers (wholesale), but end demand is retail registrations. When dealers overstock, shipments crater even if retail is stable (2022–2023 destocking); when inventories run lean, shipments can outrun retail (restocking). Winnebago explicitly warns that dealers with excess inventory may postpone orders, causing manufacturer sales to run below end-user demand [7]. Watch shipments versus registrations, not either alone [2][20].
• Dealer floorplan financing. Dealers finance their lot inventory with interest-bearing "floorplan" loans, so higher rates squeeze dealers into ordering less — a second, indirect way rates hit the factory [20]. (A 2025 federal tax change restoring full floorplan-interest deductibility for towables was a targeted relief [20].)
• For suppliers, "content per unit" is the growth lever. LCI and Patrick can grow even in a flat-unit market by selling more parts per trailer — a metric they report directly [18][11].
• Warranty and recalls are a recurring cost and reputational risk on a product the customer sleeps in. Warranty performance was a material driver of both Thor and Winnebago's recent margins [13][15].

6. What drives demand

RVs are a discretionary big-ticket purchase, so demand tracks household balance sheets and the cost of credit:

• Interest rates. The single biggest swing factor. In 2025, RV loan APRs (annual percentage rates) ran ~9.5%–13.5%, adding an estimated $150–$250 to the monthly payment on a $50,000 towable financed over 15 years; subprime buyers faced ~20% and were largely priced out [20]. Towables, being cheaper, hold up better than motor homes when money is tight [2].
• Consumer confidence, fuel prices, and the used market. Weak sentiment or high fuel costs push buyers down-market or into used units. Towables also require a suitable tow vehicle, making pickup/SUV prices and fuel economy relevant [7].
• Demographics — a genuine tailwind. ~8.1 million U.S. households own an RV; estimates of future purchase intent vary by methodology (RVIA's 2025 ownership survey used a materially changed methodology, so its household counts are not directly comparable with earlier series) [22][23]. The buyer base is getting younger: median owner age fell from 53 (2021) to 49 (2025), with a wave of millennial and Gen Z first-timers minted during the pandemic camping boom; median annual usage is about 30 days [22][23].
• Camping and campground capacity. Rising camping participation supports demand — KOA reports more than 52 million North American households camped in 2025 [24] — while campsite availability can cap it.
• Replacement cycle and the installed base. A large, aging fleet generates steady replacement demand that partly cushions downturns.
• Substitution. Used RVs, tent camping, rental RVs, hotels, cruises, vacation homes, boats and motorcycles all compete for the same discretionary budget.

7. Regulation

Towable RVs are regulated as vehicles, not housing — an important distinction:

• NHTSA / FMVSS. As highway vehicles, trailers must meet the National Highway Traffic Safety Administration's Federal Motor Vehicle Safety Standards (Title 49 of the Code of Federal Regulations) covering lighting, brakes, tires and the like. Manufacturers must self-certify compliance, assign VINs, affix certification labels, report safety defects and conduct recalls [25][26].
• NFPA 1192. The construction, fire-safety, plumbing, electrical and LP-gas standard is NFPA 1192, Standard on Recreational Vehicles, from the National Fire Protection Association, revised on a three-year cycle [27]. Park models follow ANSI A119.5 (American National Standards Institute) [25].
• Self-policing via RVIA. The RV Industry Association (RVIA) runs a certification and unannounced factory inspection program (roughly every eight weeks) to enforce NFPA 1192 compliance; the RVIA seal is the industry's badge [27].
• Composite-wood formaldehyde rules. EPA's TSCA Title VI rules cover hardwood plywood, medium-density fiberboard and particleboard and impose certification, labeling and recordkeeping requirements; EPA's compliance material expressly identifies travel-trailer and camper manufacturers as affected fabricators [28].
• The HUD exemption. Because they are certified as RVs, travel trailers are exempt from the U.S. Department of Housing and Urban Development (HUD) manufactured-home code — the boundary that keeps "tiny homes on wheels" a recurring regulatory gray area [25].
• State-level rules. State lemon laws, dealer/franchise regulations, registration requirements, dimensional limits and consumer statutes add jurisdictional complexity [7].
• Trade and tariffs (a live 2025 issue). Section 232 tariffs on steel and aluminum rose from 25% to 50% in mid-2025, and a September 2025 proclamation extended tariffs to softwood lumber and wood products — including the imported lauan plywood the industry relies on [21]. These raise input costs that builders largely pass through to buyers. Winnebago reports that tariffs have increased sourcing costs and can cause supply disruptions [7].

8. Competitive dynamics and consolidation

The industry has consolidated into an oligopoly at the top and a fragmented tail below. Thor and Forest River together hold 80%-plus of the U.S. RV market; add Winnebago's Grand Design and the top three effectively own the branded towable business — in travel trailers specifically (275,251 units in 2024), Thor held ~41%, Forest River ~33.8% and Grand Design ~7.6% [16][12]. At the ownership level, Patrick Industries estimates the three largest groups controlled approximately 86% of towable retail unit share in 2025 [11]. The federal four-firm concentration ratio of 71.4% confirms the same picture for the broader NAICS code [8].

Consolidation has come through acquisition: Berkshire bought Forest River (2005); Winnebago bought Grand Design (2016) and Newmar (2019); Thor rolled up Jayco and, in Europe, Erwin Hymer. Brand proliferation creates an appearance of fragmentation that is not supported by ownership-level market shares — Thor cites approximately 80 U.S.-and-Canadian RV manufacturers, but the three largest groups control the vast majority of units [13]. Truly independent builders now command premium, niche pricing (Airstream being the iconic example, owned by Thor). The supplier side is consolidating too, with LCI and Patrick acquiring component makers to raise content per unit. Competitive advantage rests on brand, dealer relationships, cost discipline and the ability to flex production — not on proprietary technology.

9. Risks

• Cyclicality above all. This is one of the most rate- and confidence-sensitive consumer-durables industries; peak-to-trough unit declines of 40%+ within two years are normal, not tail events. Towable shipments fell from 544,028 in 2021 to 267,295 in 2023 — a 51% collapse in two years [3][4].
• Channel (inventory) whipsaw. Because factories sell to dealers, a destocking cycle can gut shipments even when retail is only softening. When retail demand slows, manufacturers suffer both the retail decline and dealer destocking [20][7].
• Input-cost and tariff exposure. Aluminum, steel and imported wood tariffs directly compress margins or raise prices into a price-sensitive market [21][7].
• Affordability ceiling. Rising sticker prices plus high financing costs can push the payment beyond the mass-market buyer, capping volume [20].
• Geographic concentration. ~86% of North American output in one Indiana region concentrates labor, weather, infrastructure and supply-chain risk [12].
• Customer/dealer concentration and financing. Heavy reliance on a small number of large dealer groups (FreedomRoads alone is 14% of Thor sales [13]) and on floorplan credit availability.
• Labor and workplace safety. The 2024 BLS incidence rate for recordable injuries and illnesses in NAICS 336214 was 6.0 cases per 100 full-time-equivalent workers, versus 3.2 for transportation-equipment manufacturing overall [29]. The Elkhart concentration can magnify skilled-labor shortages during upcycles and layoffs during destocking.
• Quality and warranty. A defect in a supplied axle, appliance, electrical system or frame can affect many brands and require recalls, field service and dealer reimbursement. Product quality also affects resale values and brand loyalty in a category where online owner communities rapidly publicize defects [13][15].
• Forecast risk. As of the Summer 2026 outlook, RVIA cut its 2026 wholesale projection to a 314,000-unit median (roughly −8% versus 2025), signaling renewed macro headwinds after two years of recovery [30]. Through May 2026, total RV shipments were already down 14.4% year-over-year and towables down 17.2% [31].

10. How to invest and the outlook

Public routes. Direct manufacturer exposure is essentially Thor (THO) and Winnebago (WGO) — both cyclical, both pay dividends, both trade at low multiples in downturns and can re-rate hard in recoveries. For a smoother read on the same demand, the suppliers LCI (LCII) and Patrick (PATK) capture "content per RV" growth across all builders, and Camping World (CWH) offers the retail/service angle (service and finance income are less cyclical than new-unit sales). Berkshire Hathaway (BRK.B) gives indirect, heavily diluted exposure to market-leader Forest River. Because the group moves together and violently, position sizing and entry point matter more than stock selection.

Private routes. The big brands are not buyable, but private capital can pursue: independent or specialty trailer/camper builders (the long tail of ~575 firms); RV dealerships (a roll-up theme already underway); the component supplier base; and adjacent RV-park and campground real estate, which monetizes the same demographic tailwind with a different, income-oriented risk profile. The attractive niches are differentiated lightweight or premium products, recurring parts and service, and suppliers with content growth across multiple OEMs. Central underwriting hazards are customer concentration, working-capital swings, warranty reserves, dealer floorplan exposure and the temptation to capitalize peak-cycle earnings.

Near-term drivers to watch (forward-looking). (1) The rate path — cuts would revive both consumer loan affordability and dealer floorplan economics, the fastest lever for the whole complex. (2) Wholesale shipments versus retail registrations — the destock/restock signal. (3) Tariff developments on steel, aluminum and lauan plywood, which set the input-cost floor. (4) The younger-buyer trend and the broader camping participation base (~52 million households [24]) — the structural demand story that, if it holds, lengthens the recovery beyond a single rate cycle. The base case entering 2026 is a mature, consolidated industry with a real demographic tailwind but a soft near-term unit forecast — an operationally sound business whose equity returns are governed mostly by where you are in the interest-rate cycle.
