Motor Home Manufacturing (United States) — NAICS 336213

1. Overview

Motor Home Manufacturing is the business of building drivable recreational vehicles (RVs) — self-propelled homes on wheels with a built-in engine and cab, sold as Class A, Class B, and Class C motorhomes. It is a small, highly concentrated slice of the wider RV industry: in the United States a few large manufacturers build nearly all the product, mostly in northern Indiana around Elkhart, the self-styled "RV Capital of the World" — Indiana accounted for 67% of motorhome shipment value in the most recent Census industry analysis [15][19].

Why an investor cares: motorhomes are one of the most cyclical big-ticket consumer purchases in the economy. A new motorhome routinely costs more than a car — from roughly $50,000 for an entry Class C to well past $500,000 for a luxury Class A diesel, with premium brands ranging from approximately $143,000 to $1.7 million [14][6] — so demand swings hard with consumer confidence, interest rates, and the credit cycle. That makes the sector a leveraged bet on the discretionary consumer: it falls fast in downturns and rebounds fast in recoveries.

Public-market investors can own the industry directly through a short list of RV makers listed on U.S. exchanges. Private investors mostly encounter it through the largest builder (Forest River, owned by Berkshire Hathaway), through independent and custom coach builders, and through adjacent plays — component suppliers, dealer roll-ups, and RV-park real estate. The specific tickers and routes are in Sections 4 and 10; the body of this primer treats motorhome manufacturing as an industry, not a stock.

2. What it is and how it's structured

NAICS (North American Industry Classification System) code 336213 covers establishments primarily engaged in manufacturing motor homes on purchased chassis or manufacturing conversion vans on an assembly-line basis — the drivable RV with integrated motor and living quarters. Manufacturers do not build the engine or running gear; they buy a bare chassis from an automaker (major suppliers include Mercedes-Benz, Stellantis, Freightliner, Ford, and Spartan) and construct the living quarters and body on top [6][11][14].

The three product classes:

• Class A — the largest, bus-shaped coaches on heavy truck chassis, gas or diesel ("diesel pushers"); the luxury end of the market.
• Class B — camper vans built inside a factory van shell (Mercedes-Benz Sprinter, Ram ProMaster, Ford Transit); compact and the fastest-growing class in recent years.
• Class C — the familiar cab-over design on a cutaway van or truck chassis; the entry point to motorized RVing and the highest-volume motorhome class, about 58–59% of motorhome shipments [16].

What the code excludes (this matters for sizing the industry):

• Travel Trailer and Camper Manufacturing (NAICS 336214) — towable RVs: travel trailers, fifth wheels, folding campers, truck campers. Towables are roughly 85–90% of all RV units shipped, so the motorized code captures only the minority segment [1].
• Motor vehicle chassis and bodies (NAICS 336111, 336112, 336211) — the chassis is bought in, not counted here.
• Recreational Vehicle Dealers (NAICS 441210) — the retail side.
• Manufactured/mobile homes — a separate housing category.
• One-off van customization — not assembly-line production.
• Component and parts suppliers, classified under their own product codes.

Ownership mix: almost entirely for-profit corporations, and unusually consolidated. The federal count is 58 firms operating 71 establishments [2][3]. Three corporate families — Thor Industries, Berkshire Hathaway's Forest River, and Winnebago Industries — together account for roughly 90% of the overall U.S. RV market, and the motorhome segment is even more top-heavy [9].

3. How big it is

Federal statistics for NAICS 336213 (motorhomes only):

The concentration figures are the story: the top four firms sell more than four-fifths of the output, the top twenty sell essentially all of it, and the HHI of about 2,023 sits in the "moderately-to-highly concentrated" zone. (HHI sums the squared market shares of all firms; U.S. antitrust agencies treat 1,800+ as highly concentrated.)

Caveats on the federal figures. This is not an industry that federal statistics undercount through tiny or informal operators — the opposite. With 58 firms and 82.5% CR4, the population is well captured. The important caveats are definitional and cyclical:

1. Narrow by design. The $7.41 billion counts drivable motorhomes only. The broader RV manufacturing business — dominated by towables (NAICS 336214), dealers, and parts — is several times larger. Total RV shipments were approximately 342,000 units in 2025, of which motorhomes were roughly 36,000 (RVIA's prose and table figures differ slightly: 36,029 versus 36,007 units; the discrepancy is preserved rather than silently reconciled) [1].
2. Diversified parents dwarf the code. The public leaders span towables, Europe, and marine, so their consolidated revenue (Thor reported $9.58 billion in fiscal 2025 [5]) is far above the motorhome-only receipts.
3. 2022 was a peak. The Economic Census snapshot lands on a pandemic-boom year; motorhome volumes have since fallen well below their 2021 record before stabilizing, so $7.41 billion overstates the current run-rate [1][5].

For scale, third-party market-research firms put the global motorhome market near $37 billion in 2024 — a different, retail-value, worldwide measure that should not be compared directly with the U.S. factory-shipment receipts above [18].

4. The investable universe

Relatively few pure ways in exist, and none is a motorhome-only stock — motorhomes are a segment inside larger RV companies.

The four corporate groups (Thor, Forest River/Berkshire, Winnebago, and the former REV organization now within Terex) together represented 89.5% of 2025 U.S./Canada motorized retail registrations, based on Statistical Surveys data cited by Thor [20].

Adjacent public plays give exposure to the same demand without picking a builder: LCI Industries (NYSE: LCII, the Lippert components maker) and Patrick Industries (NASDAQ: PATK) supply parts to every RV plant, and Camping World Holdings (NYSE: CWH) is the largest RV dealer. These trade on RV volumes broadly, not motorhomes specifically.

Private and other owners: Forest River (via Berkshire) is the big one that cannot be bought as a standalone. Two former independents were absorbed by the public leaders — Tiffin by Thor (2020) and Newmar by Winnebago (2019). The remaining private field is small independent and custom builders (for example NeXus RV and various Class B van up-fitters), which occasionally attract private-equity or venture capital.

5. How the money works

Motorhome builders run an assembly, mix, and channel business, not a rate base or a fee stream. They are better understood as complex assemblers and integrators than as vertically integrated automakers: they fabricate the body and interior and integrate electrical, plumbing, heating, cooking, refrigeration, water, and waste systems, but generally purchase the chassis, engine, generator, and appliances [6]. The metrics that matter:

• Wholesale unit shipments and average selling price. Manufacturers book revenue when a unit ships to a dealer, not when a consumer buys it. Volume × price per unit drives the top line, and mix matters enormously — a single Class A diesel can carry the sticker of five entry Class C units [14].
• Gross margin and operating leverage. These are relatively low-margin assembly operations with high fixed costs (plants, tooling, labor). Thor's North American Motorized segment ran a 9.7% gross margin in fiscal 2025 (down from 11.4% in FY2024), with material, labor, outbound freight, and warranty together at 84.1% of sales; segment pretax income was $85.3 million, or about 3.9% of sales [5]. Winnebago's Motorhome segment posted a $7.3 million operating loss (negative 0.6% margin) in FY2025, versus $52.9 million operating income (4.1% margin) the prior year, despite higher average selling prices — volume deleverage and heavier discounts overwhelmed richer mix [6]. When volumes fall, fixed costs are spread over fewer units and margins compress fast ("deleverage"); when volumes rise, incremental margins are strong.
• The dealer channel and floor-plan financing. Dealers hold inventory using floor-plan loans (bank financing secured by the units on the lot). Winnebago disclosed that two floorplan lenders held approximately 51% of its financed dealer-inventory dollars at fiscal year-end [6]. This is the industry's central dynamic: in 2021–2022 makers over-shipped, dealers over-stocked, and the 2023–2024 correction forced destocking, discounting, and "dealer assistance" that hammered margins [7][12]. Wholesale shipments can therefore diverge sharply from retail registrations for a year or more.
• Backlog. Orders on the books signal near-term demand. Thor's North American Motorized backlog rose 29.3% to $1.005 billion at the end of fiscal 2025 — a reported sign of channel restocking [5]. However, dealer orders can often be postponed or cancelled without penalty, making backlog a weaker leading indicator than in other industries.
• Input costs. Chassis (bought from automakers), aluminum, steel, lumber, resins, and appliances. Commodity exposure includes steel, aluminum, fiberglass, wood, copper, rubber, and lumber. Chassis availability and price are a swing factor the builders do not fully control; a disruption at a chassis supplier can halt an otherwise largely complete vehicle [6].

In short, owners make money by keeping plants full at a favorable product mix, holding the line on discounts, and matching shipments to real retail demand so the dealer channel does not choke on inventory.

6. What drives demand

• Interest rates and credit. The single biggest lever. Motorhomes are financed purchases, so retail loan rates set affordability, and dealer floor-plan costs set how much inventory dealers will carry. Higher rates hurt twice: monthly payments rise for buyers and carrying costs rise for dealers. Falling rates are the industry's main hoped-for tailwind [10].
• Consumer confidence and the macro cycle. A motorhome is a deferrable luxury; buyers pull back first in uncertainty and return when confidence recovers [17].
• Demographics and the camping trend. RV ownership has broadened and gotten younger — the median owner age fell from 53 in 2021 to 49 in 2025, and about 11.2 million U.S. households own an RV with 16.9 million more expressing strong interest in ownership [10][22]. Younger families and remote workers have widened the buyer base beyond retirees.
• Fuel prices. A secondary factor. Motorhomes are fuel-thirsty, so high pump prices dent usage and sentiment, but interest, insurance, and storage costs weigh more on the purchase decision [17].
• Substitution in downturns. RV travel can be materially cheaper than flying and hotels, so some buyers "trade down" to RV vacations even in soft economies — a partial cushion on the demand side [17].

The recent cycle. Motorhome shipments swung hard: 56,212 units in 2021, 58,410 in 2022 (pandemic peak), then down sharply to 45,879 in 2023 and 34,891 in 2024 before recovering modestly to roughly 36,000 in 2025 [1][23][24][25]. Through May 2026, motorhome shipments were 17,739, up 11.8% year over year even as total RV shipments fell 14.4% — with Type B and Type C classes up 12–18% while Type A declined, indicating demand shifting toward smaller, more maneuverable motorhomes [26].

7. Regulation

Because a motorhome is a motor vehicle, it sits under vehicle regulators rather than a building code:

• NHTSA and FMVSS. The National Highway Traffic Safety Administration enforces Federal Motor Vehicle Safety Standards, manufacturer certification, labeling, defect reporting, and safety recalls on motorhomes. As completed motor vehicles, motorhomes remain subject to NHTSA free-remedy obligations [11][27].
• Voluntary industry standards (RVIA/ANSI/NFPA). The RV Industry Association (RVIA) certifies member plants to consensus standards for LP-gas, electrical, plumbing, and fire safety and runs more than 2,000 unannounced plant inspections a year; the RVIA seal is the market's de facto quality gate. These include NFPA requirements governing fire and life safety, fuel systems, plumbing, and vehicle systems [11][28]. Notably, RVs are not subject to the federal HUD manufactured-housing code. The voluntary-industry regimes do not replace federal vehicle-safety liability.
• EPA and CARB emissions. The Environmental Protection Agency and the California Air Resources Board regulate emissions at the chassis level. CARB's Advanced Clean Trucks (ACT) rule requires chassis makers to sell rising percentages of zero-emission vehicles, and because there is no viable zero-emission motorhome chassis yet, some suppliers have paused sales of conventional motorhome chassis in California and states that follow its rules — a real near-term supply constraint [12].
• State franchise and consumer laws. Dealer-franchise statutes and state "lemon laws" govern the retail channel and warranty exposure.

8. Competitive dynamics and consolidation

The industry has consolidated into a handful of acquisitive families. Thor grew by buying Jayco (2016), Germany's Erwin Hymer Group (2019), and Tiffin (2020); Winnebago added Grand Design (2016) and Newmar (2019) plus marine brands; Berkshire's Forest River expanded its brand stable organically and by acquisition [9]. The latest move: Terex completed its merger with REV Group on February 2, 2026, folding REV's RV brands (American Coach, Fleetwood, Holiday Rambler, Renegade, Midwest Automotive Designs) into a larger specialty-equipment company and removing REV as a standalone listed RV exposure [7][13][21].

Brand diversity materially overstates corporate competition — numerous brands roll up to the four major groups. Competition runs on brand, dealer relationships, product mix, and — critically — inventory discipline. Because a few makers dominate, the sector's swings are amplified: when the leaders all chase share with discounts, motorhome margins compress across the board [6][7]. The supplier side is also concentrated (Lippert and Patrick), and the dealer side is consolidating around Camping World, so bargaining power is contested up and down the chain.

9. Risks

• Deep cyclicality. Motorhomes are among the first purchases cut in a downturn and the motorized segment is more expensive and more volatile than towables. Shipments fell from a 2022 peak of 58,410 to 34,891 in 2024 before stabilizing [1][5][25].
• Interest-rate sensitivity — twice over. Rates hit both consumer affordability and dealer floor-plan costs, so a higher-for-longer environment squeezes demand and channel inventory simultaneously [10].
• Channel whipsaw. The gap between wholesale shipments and retail sales can force destocking and heavy discounting, as in 2023–2024 [7].
• Chassis dependence and emissions rules. Reliance on a few automakers for chassis, plus CARB/ACT constraints with no zero-emission motorhome chassis available, threaten supply and could strand demand in regulated states. Winnebago explicitly notes that motorhome chassis come from a small supplier group and that raw-material and tariff increases may not be recoverable through pricing [6][12].
• Input-cost and tariff exposure. Aluminum, steel, lumber, and imported components move margins and are sensitive to trade policy.
• Labor constraints. Assembly remains labor-intensive, and production is clustered in northern Indiana and Iowa. Competition for industry-skilled workers can raise wages or limit how quickly output can respond during periods of strong demand [5].
• Warranty and recall risk. A motorhome combines a vehicle, house, and multiple third-party systems. Failures can involve either the OEM's integration work or a supplier's chassis, appliance, or electrical component, complicating responsibility and repair.
• Concentration risk for owners. With so few players, a single manufacturer's share-grab or a supplier's stumble reverberates industry-wide.
• Used-market and affordability drag. A large used-RV inventory competes with new units, and record-high new prices test the entry buyer [14].

10. How to invest and the outlook

Public routes. The cleanest is Thor Industries (THO) — the global RV leader at roughly 47.5% U.S./Canada motorized share, though motorhomes are one segment of a $9.6-billion company that also includes towables, European RVs, and components [5][8][20]. Winnebago (WGO) offers a smaller, three-segment RV-plus-marine mix at about 15% motorized share [6][20]. Following the February 2026 merger, Terex (TEX) provides indirect exposure to the former REV motorhome portfolio, alongside a much larger specialty-equipment business — diluting the RV exposure [7][13][21]. To play RV demand without picking a builder, the component suppliers LCI Industries (LCII) and Patrick Industries (PATK) and the dealer Camping World (CWH) move with the same cycle; these may benefit from installed-base service and aftermarket activity when new-unit manufacturing is weak. Both Thor and Winnebago pay quarterly dividends, and Thor has a multi-year record of annual increases — one reason the group is often treated as a cyclical value/dividend position rather than a growth story. Forest River is only reachable indirectly, as an immaterial piece of Berkshire Hathaway (BRK.B).

Private routes. Direct private ownership is scarce: Forest River is inside Berkshire, and the two big independents (Tiffin, Newmar) have been absorbed. What remains for private capital is small independent and custom coach builders, Class B van up-fitters, and — more accessibly — the adjacent value chain: component suppliers, dealer roll-ups, and RV-park/campground real estate, which capture RV-travel growth without factory-cycle risk. For an OEM acquisition, the critical diligence is normalized retail registrations rather than wholesale shipments alone; dealer inventory by model year; cancellable backlog; chassis allocations and alternative chassis engineering; floorplan repurchase exposure; warranty cost by production cohort; dealer and supplier concentration; labor flexibility; and earnings normalized across the full cycle.

Near-term outlook (forward-looking). After a hard 2022–2024 correction, the industry has stabilized: total RV shipments grew 2.5% to approximately 342,000 units in 2025 and motorhomes rose 3.3% to roughly 36,000, with RVIA forecasting modest further growth into 2026 [1]. Through May 2026, motorhome shipments were up 11.8% year over year even as the broader RV market declined, with strength in Class B and C offsetting softer Class A demand [26]. Rebuilding backlogs (Thor's motorized backlog up 29%) point to channel restocking [5]. The bull case rests on falling interest rates, normalized dealer inventories, and a younger, broader buyer base [10]. The bear case is a rate-and-confidence relapse, the CARB chassis bottleneck, and renewed discounting among a concentrated field of makers [7][12]. Either way, this remains a leveraged, cyclical read on the U.S. discretionary consumer — high torque in both directions.
