Forest River is one of the largest RV manufacturers in the world, producing travel trailers, fifth wheels, motorhomes, and toy haulers under dozens of brand names — including Rockwood, Cherokee, Flagstaff, Coachmen, Wildcat, Cardinal, and many more. If you own a Forest River product, chances are good that several of the appliances and components in your rig are the same ones found in hundreds of thousands of other rigs on the road.
That's actually good news for parts availability. Most Forest River RVs are built with appliances and components from a short list of well-known suppliers — Suburban, Dometic, Atwood, Lippert, Furrion, and WFCO among them. That means when something fails, you're almost never chasing an obscure proprietary part. You're looking for a standard industry replacement that's widely stocked.
This guide covers the most common Forest River component failures by system, the replacement parts most often needed, and where to find them at a discount.
Forest River RV Brands: What You Might Own
Forest River operates a large portfolio of RV brands. You may own a Forest River product without realizing it — here are some of the most common names under their umbrella:
- Travel Trailers: Rockwood, Cherokee, Flagstaff, Salem, Surveyor, Wildwood, Puma, Cherokee Wolf Pack
- Fifth Wheels: Cardinal, Wildcat, Sabre, Sierra, Cedar Creek, Sandpiper
- Toy Haulers: Work and Play, Wildcat Maxx, XLR
- Motorhomes: Berkshire, Georgetown, Forester, Sunseeker, Coachmen Leprechaun, Dynamax
- Destination Trailers: Shasta, Prime Time, Rockwood Signature
Regardless of which brand name is on your rig, the appliances and components inside follow the same industry-standard parts ecosystem.
Most Common Forest River Failures by System
Furnace
Forest River rigs are most commonly equipped with Suburban or Atwood/Dometic furnaces. The most frequent furnace issues in Forest River RVs are ignition failures (dirty or failed electrode, failed control board) and blower motor failures — both of which are parts-level repairs rather than full replacements. Full furnace replacement becomes the right call when a unit is older than 10–12 years or has a failed heat exchanger.
Common BTU sizes in Forest River rigs: 16,000, 20,000, 25,000, and 30,000 BTU for travel trailers; 30,000–35,000 BTU for larger fifth wheels and motorhomes.
Most commonly replaced: Furnace ignitor electrode, DSI control board, blower motor, full furnace replacement (Suburban SF series or Dometic DFMD series).
Water Heater
Forest River installs both Suburban and Atwood/Dometic water heaters across their lineup. Common failures include pilot light issues (thermocouple on Suburban models), failed electric heating elements, and anode rod depletion on Suburban units. After 10–15 years, full tank replacement is often more economical than continued repairs.
Most commonly replaced: Thermocouple, anode rod (Suburban models), electric heating element, full water heater (Suburban SW6DE, SW10DE, or Atwood/Dometic equivalent).
Air Conditioner
Forest River uses Dometic and Coleman-Mach rooftop air conditioners across most of their lineup, with Furrion appearing on newer builds. The most common AC failures are capacitor failures (very common and inexpensive to fix), dirty coils causing poor performance, and full compressor failure on older units (usually prompts replacement).
Most commonly replaced: Run capacitor, air filter, full rooftop AC unit (Dometic Penguin II, Dometic Freshjet 3, or Dometic Freshjet 5).
Slide-Out System
Forest River uses Lippert slide-out systems extensively — including Schwintek in-wall systems and hydraulic systems on larger units. The IG-42 motor (part #236575) is the most commonly replaced component in Schwintek systems, followed by control board failures. Rack wear becomes an issue on high-mileage slides that weren't properly lubricated.
Most commonly replaced: Lippert IG-42 slide-out motor, Schwintek control board, slide-out gear rack.
Roof
Forest River travel trailers and fifth wheels predominantly use EPDM rubber roofing, with newer builds increasingly using TPO. Roof sealant failures around vents and at the front cap seam are by far the most common issue — and the most preventable with annual maintenance. Full roof membrane replacement is typically needed at the 10–15 year mark.
Most commonly replaced: Dicor lap sealant (annual maintenance), full EPDM or TPO membrane replacement, vent covers, roof vent lids.
Power Converter
Most Forest River rigs ship with a WFCO converter/distribution panel. Converter failures are most often identified when batteries won't charge on shore power or when 12V appliances run dim. WFCO replacement units are among the most stocked RV parts in the industry.
Most commonly replaced: WFCO 8900 or 8955 series converter/distribution panel, circuit breakers, fuses.
Awning
Forest River equips most of their travel trailers and fifth wheels with Carefree or Dometic power awnings, with Lippert Solera appearing on many newer builds. Motor failures are the most common issue — typically caused by water intrusion into the roller tube over time.
Most commonly replaced: Awning motor (Dometic 9100, Lippert Solera 373566), awning fabric.

How to Find the Right Part for Your Forest River
Because Forest River builds dozens of brands and models, the fastest way to confirm you're ordering the right part is to identify the component manufacturer — not the Forest River brand. Here's how:
- Furnace and water heater: Look at the exterior access panel — the appliance brand (Suburban or Atwood/Dometic) and model number are printed on a label
- Air conditioner: The brand and model are on a label on the rooftop shroud or the interior ceiling unit
- Slide-out: Check the end cap of the roller tube or the motor housing itself for the Lippert model designation
- Awning: Brand and model are typically on a label on the awning arm or end cap
- Converter: Open the power center door — the WFCO model number is on the front of the unit
With the component brand and model number in hand, finding the right replacement part is straightforward — and you're no longer dependent on what a Forest River dealership has in stock.
Where to Buy Forest River Replacement Parts at a Discount
Forest River dealerships are convenient for warranty work, but for out-of-warranty repairs they're rarely the most cost-effective option. Because the appliances and components in Forest River RVs are industry-standard parts from Suburban, Dometic, Lippert, WFCO, and others, you can source them directly from RV parts suppliers at significantly lower prices than dealer list price.
At The RV Surplus, we specialize in exactly these parts — furnaces, water heaters, air conditioners, slide-out motors, converters, awning components, and roofing materials — at discount prices with free shipping to the continental U.S. We carry both new units and new-condition surplus stock from the same manufacturers that supply Forest River directly.
Frequently Asked Questions
What appliances does Forest River use in their RVs?
Forest River sources appliances from the same major suppliers used across the RV industry — primarily Suburban and Atwood/Dometic for furnaces and water heaters, Dometic and Coleman-Mach for air conditioners, Lippert for slide-out and leveling systems, WFCO for power converters, and Carefree, Dometic, or Lippert Solera for awnings.
Can I buy Forest River replacement parts without going to a dealer?
Yes — for the vast majority of repairs. Since most components are industry-standard appliances from third-party manufacturers, you can source them directly from RV parts suppliers. You only need to go through a Forest River dealer for structural body parts, proprietary cabinetry, or warranty-covered repairs.
How do I find my Forest River's component model numbers?
Each appliance has a label with the manufacturer name and model number. Check the exterior access panels for the furnace and water heater, the rooftop shroud for the AC, and the power center door for the converter. Your RV's owner's manual should also list the appliance models installed from the factory.
Are Forest River RVs good quality?
Forest River produces a wide range of products across many price points — quality varies significantly by brand tier and model year. Entry-level models prioritize affordability; mid-range and premium brands like Cedar Creek and Berkshire are built to a higher standard. As with any RV, consistent maintenance and prompt attention to small issues is the biggest factor in long-term reliability.
What is the most common repair on a Forest River RV?
Roof sealant maintenance is far and away the most common issue — and the most preventable. Annual inspection and resealing of all roof seams, vent bases, and cap seams prevents the water intrusion that causes the most expensive RV damage. After roof maintenance, furnace ignition issues and slide-out motor replacements are among the most frequent repairs we see.
