What an RV repair actually costs in 2026, by category, with real shop pricing ranges and what to ask before you authorize work. Written by Mile High RV Works in Denver, the shop that also builds custom food trucks under Mile High Foodtrucks. About 9,500 words. Every number is what we have actually seen across hundreds of RV repair quotes in the Front Range.
Why RV repair is expensive (and how to keep it sane)
The average RV owner spends $1,800 to $3,500 a year on repairs and maintenance. That figure climbs with rig age and depending on what fails. The expensive surprises are the slide-out failures, roof replacements, generator rebuilds, and absorption refrigerator deaths. Routine work (oil, brakes, awning fabric, tank valves) is more predictable.
The reason RV repair runs higher than auto repair: RVs are a house plus a vehicle, and the house parts are not standardized. Every brand uses different slide mechanisms. Roof materials change every few years. Appliances are RV-specific (Norcold, Dometic, Atwood) and parts are sometimes discontinued. Add the labor time for working in confined spaces and getting access behind walls, and the bill grows.
The good news: about 60 percent of repair calls are for things that can be prevented with annual roof inspections, generator service, and seal maintenance. Operators who do the preventive work cut their annual repair bill in half.
The 8 most common RV repairs (and what they cost)
Industry-wide, these are the repair categories that show up most often. Pricing reflects Denver-area shop rates in 2026.
1. Roof repair (the #1 RV failure)
Roofs leak. Sealants fail. Vents and AC mounts are the first to go. A small leak that goes undetected for one season becomes rotten plywood and bubbling sidewalls.
| Service | Range | What's involved |
|---|---|---|
| Roof inspection | $150-$300 | Walk roof, photograph problem areas, write report |
| Reseal seams & vents | $400-$900 | Strip old caulk, prep, lap sealant or Eternabond tape |
| Patch repair (small) | $300-$700 | EternaBond/Dicor patch over isolated damage |
| Soft spot fix | $1,200-$3,500 | Open the roof, replace rotted decking, reseal |
| Full roof replacement | $6,000-$14,000 | Strip entire roof, replace membrane (TPO/EPDM), reseal all penetrations |
The single best money you can spend on an RV: an annual roof inspection. $200 once a year prevents $8,000 problems later.
2. Slide-out repair (the most expensive surprise)
Slides are mechanical systems that fail. Three main types: hydraulic (most Class A), electric (most fifth wheels, travel trailers), and cable-driven (older units). Each fails differently.
| Service | Range | What's involved |
|---|---|---|
| Slide seal replacement | $400-$1,200 | Pull old seal, clean track, install new |
| Hydraulic line repair | $500-$1,800 | Pinpoint leak, replace line/cylinder, refill, test |
| Electric motor replacement | $700-$1,800 | Diagnose, source motor, replace, sync |
| Cable replacement | $900-$2,200 | Pull cables, replace, re-tension |
| Full slide rebuild | $3,500-$8,500 | Remove slide, rebuild mechanism, reseal, retest |
Slides that drift, drag, or refuse to retract are almost always a hydraulic pressure problem or a worn cable. We do the diagnostic first because the wrong fix on a slide makes it worse. More on slide-out repair.
3. Generator service (preventive saves you thousands)
Onan QG and HDKCA series are the workhorse generators in most RVs. Cummins Onan is the dominant brand. Generac is less common in RVs but growing.
| Service | Range | When to do it |
|---|---|---|
| Annual service | $200-$450 | Oil, filter, spark plug, fuel filter, air filter |
| Carb cleaning/rebuild | $350-$700 | Won't start, runs rough, after long storage |
| Voltage regulator | $400-$900 | Output voltage wrong or unstable |
| Brush replacement (older units) | $300-$650 | Power output dropping over time |
| Full generator replacement | $5,500-$11,000 | When repair cost exceeds replacement |
Generator life expectancy: 4,000-8,000 run hours with annual service. Without service, half that. Full generator service guide.
4. Awning repair and replacement
Power awning motors fail. Fabric tears. Manual awning arms bend in wind. Slide toppers wear faster than main awnings.
| Service | Range |
|---|---|
| Fabric replacement (manual, 12-21ft) | $350-$750 |
| Fabric replacement (power, 14-21ft) | $450-$1,100 |
| Slide topper replacement | $300-$700 per slide |
| Awning motor replacement | $400-$850 |
| Arm replacement (per arm) | $250-$500 |
| Full power awning replacement | $1,400-$2,800 |
5. Electrical system repair
RV electrical is a beast: 12V DC house systems, 120V AC shore/generator power, inverter/charger, converter, solar. When one component fails it often masquerades as a different problem.
| Service | Range |
|---|---|
| Diagnostic (1-2 hr) | $200-$400 |
| Converter replacement | $500-$1,200 |
| Inverter/charger replacement (2000W) | $1,800-$3,500 |
| Battery bank replacement (lead-acid) | $800-$2,200 |
| Lithium battery upgrade (200Ah) | $2,500-$5,500 |
| Solar install (400W full kit) | $3,000-$6,500 |
| Transfer switch replacement | $400-$900 |
6. Plumbing and tank repair
Fresh water, grey water, black water. Tanks crack. Valves leak. Pumps die. Sensors stop reading right.
| Service | Range |
|---|---|
| Water pump replacement | $250-$550 |
| Water heater service | $200-$500 |
| Water heater replacement (6 gal) | $900-$1,800 |
| Black/grey tank valve replacement | $300-$700 |
| Tank sensor cleaning/replacement | $200-$500 |
| Cracked tank replacement | $1,200-$3,000 |
| Winterization | $120-$250 |
| De-winterization | $80-$180 |
7. Appliance repair
The four big ones: refrigerator, air conditioner, furnace, water heater (covered above). Norcold and Dometic dominate the fridge market. Atwood and Suburban dominate furnaces.
| Service | Range |
|---|---|
| Fridge diagnostic | $150-$300 |
| Fridge cooling unit replacement | $1,800-$3,500 |
| Residential fridge conversion | $2,500-$5,500 |
| A/C compressor replacement | $1,200-$2,400 |
| Full rooftop A/C replacement | $1,400-$2,800 |
| Furnace ignition repair | $300-$700 |
| Furnace replacement | $900-$1,800 |
8. Body, paint, and collision
| Service | Range |
|---|---|
| Hail damage (paintless dent) | $1,500-$6,000 |
| Fiberglass sidewall patch | $600-$2,500 |
| Decal replacement (per panel) | $400-$1,500 |
| Full repaint (Class A) | $8,000-$20,000+ |
| Roof corner repair (collision) | $1,500-$4,500 |
What drives the price up or down on a repair
Four factors that change quotes on the same problem:
1. RV brand and age. 1998 Winnebago slide motor: $400 in parts if we can find it, sometimes more if discontinued. 2023 Grand Design slide motor: $250, in stock. Newer rigs have parts. Older rigs sometimes need custom fabrication.
2. Access difficulty. Roof leak directly over a fixed bunk: more labor to open the ceiling. Same leak over a slide-out: easier access. Quotes reflect access time.
3. Cascading damage. A small slide seal failure that went unnoticed for two years: now there's wall rot too. The quote includes fixing both. The owner who caught it early just pays for the seal.
4. Parts availability. Norcold N841 cooling units are scarce. We sometimes have to wait 4-6 weeks. Common Atwood water heater elements are in stock. The wait affects labor batching.
Routine maintenance schedule (do this and your repair bill stays low)
| Service | Frequency | Cost |
|---|---|---|
| Roof inspection & seal check | Annual (spring) | $150-$300 |
| Generator service | Every 150 hrs or annually | $200-$450 |
| Bearing repack (travel trailers, fifth wheels) | Every 12-15K miles | $300-$600 |
| Brake adjustment/check (towables) | Annual | $120-$300 |
| Battery service | Annual or before long storage | $60-$150 |
| Slide seal lubrication | Twice a year | $80-$200 |
| Winterization | Annual | $120-$250 |
| Fridge defrost & level check | Annual | $80-$150 |
Total annual maintenance bill for an attentive owner: $800-$1,500. Total repair bill avoided: often $3,000-$10,000.
Warranty repair vs out-of-pocket
Three types of warranty matter:
1. Manufacturer warranty. Most RVs have 1-2 year limited warranty on the rig. Coach companies vary: some honor warranty work at independent shops with prior approval, some require dealer-only. Dealer service backlogs are often 6-12 weeks. Independent shops like us can sometimes get authorization for the same work with a 2-week timeline.
2. Extended warranty / service contracts. Companies like Good Sam Extended Service Plan, Wholesale Warranties, RV PlusONE, Cornerstone United. Coverage varies dramatically. Some are golden, some are useless. The good ones authorize independent shops directly. The bad ones make you wait weeks for approval and deny common claims.
3. Component warranties. Specific parts (some appliances, slide-out systems, generators) have manufacturer warranties separate from the RV. Onan generators come with 2-3 year warranty. Norcold/Dometic refrigerators 1-2 years. Always ask: even out-of-coverage, sometimes a goodwill repair is possible if the failure is on a known issue.
We work with all major extended warranty companies. We handle the authorization paperwork. More on warranty repair.
Insurance claims
RV insurance covers collision, comprehensive (theft, vandalism, fire, hail), and liability. It does NOT cover wear-and-tear, leaks from old sealants, or mechanical failure.
Common covered claims:
- Hail damage to roof and sidewalls (common in Front Range during June-August)
- Tree branch impact
- Collision (you hit something, something hit you)
- Theft of appliances or accessories
- Water damage from external sources (not slow leaks)
Common DENIED claims:
- Slow roof leaks caused by failed sealant
- Slide problems caused by lack of maintenance
- Appliance breakdown (covered by extended warranty, not insurance)
- Tire blowouts (treated as wear)
We work directly with all major RV insurance carriers (Progressive, Good Sam, National General, Foremost, USAA). Photos, written estimates, and supplemental claims handled.
How we quote
The honest answer most shops will not give you: every quote has two parts. The visible work and the contingencies.
For straightforward jobs (roof reseal, water pump replacement, awning fabric), we give a firm quote. The number does not change unless you authorize additional work.
For diagnostic-required jobs (slide drift, intermittent electrical, refrigerator not cooling), we give a diagnostic price first, then a full estimate after we see what's actually wrong. Some shops skip the diagnostic and "estimate from the symptoms," then surprise you with the real cost later. We do not do that.
Common scams and how to avoid them
The RV repair industry has a reputation problem. Here are the four most common scams and how to spot them:
1. The "we found three more things" bill. You authorize a $1,200 slide repair, you get back a $4,500 invoice with three extra items added. Real shops call you and get authorization before doing extra work. If a shop won't put extra work approval in writing, walk away.
2. The "premium part" upsell. Common parts marked up 300-500 percent and sold as "the only quality option." Most RV parts have multiple manufacturers. Ask for the brand and model number. Look it up online before authorizing.
3. The unnecessary roof replacement. Reseal can fix what looks like a "needs replacement" problem in many cases. A good shop will tell you when reseal is sufficient and when full replacement is genuinely needed.
4. The diagnostic that never ends. Some shops charge for diagnostic but never give you a clear answer. They keep adding labor. A real diagnostic ends with a written cause and recommended fix within 1-3 labor hours for most problems.
Choosing a shop
Five things to verify before authorizing work:
- Written estimates. No verbal-only quotes. Get it in writing with parts and labor itemized.
- Estimate ceiling. The estimate is the max unless you authorize more. Get this in writing.
- Reviews from real RV owners. Google, Facebook, RVTrader reviews. Look for patterns, not isolated complaints.
- Insurance partnerships. Shops that work with major insurance companies have had to prove they meet quality standards.
- Workmanship guarantee. 30-90 days minimum on labor. Reputable shops stand behind their work.
FAQ
Should I take my RV to the dealer or an independent shop?
Dealers have factory training and parts but often have 8-12 week backlogs and charge premium labor. Independent shops are faster, often cheaper for the same work, and frequently more experienced because they see more variety. For warranty work, sometimes the dealer is mandatory. For everything else, independent shops are usually the better answer.
How much should I budget annually for RV repairs?
Rule of thumb: 2-4 percent of the rig's value per year for maintenance plus reserve. A $80,000 motorhome: $1,600-$3,200/year. Older rigs trend higher. Newer rigs lower.
When is it time to stop repairing and sell the rig?
When repair costs in a 12-month period exceed 50 percent of the rig's value. At that point you are pouring money into a depreciating asset.
Can I do RV repairs myself?
Many maintenance items yes: roof seal touch-ups, oil changes, awning fabric replacement, simple electrical. Some major repairs (slide rebuilds, generator overhauls, fiberglass body work) require shop equipment and knowledge. Don't tackle propane systems yourself.
Do you offer mobile service?
Currently no. Mile High RV Works is shop-based. Drive your rig to our Denver-area shop. Most Front Range customers reach us within 30-90 minutes. Shop info.
How do I prevent the most expensive repairs?
Annual roof inspection, slide seal lubrication twice a year, generator service every 150 hours, battery service before winter. These four habits prevent 70 percent of the major repair surprises.
