Every owner who drops off a rig asks the same thing: how long will my RV be in the shop? The honest answer is that most single-issue repairs need one to five days of actual shop time. The job is rarely the problem. What stretches a repair from days into weeks is waiting on a part, and what stretches it from weeks into months is a warranty authorization queue at a dealership. IDS, which tracks work orders across hundreds of RV dealerships, put the 2025 national average repair event cycle time at 30.6 days. Warranty jobs averaged 42.4 days. Jobs held up by an out-of-stock part averaged 54.3 days.
Mile High RV Works is a shop-based RV repair operation in Denver, run by the same crew that builds custom food trucks under Mile High Food Trucks. We serve the whole Front Range from one shop, so owners come to us from Denver, Boulder, Fort Collins and Colorado Springs. We are not a dealership, and we do not have a hundred units in a back lot waiting on a manufacturer to answer an email. That is most of the reason our timelines look nothing like the numbers above.

How long each RV repair actually takes
These are typical shop-time ranges once the rig is in a bay and parts are on hand. Any of them runs longer if a part has to be chased.
1. Diagnostic (same day to 3 days)
Most diagnostics take one to three labor hours. A leaking fitting or a dead water pump gets found the same day. Intermittent faults take longer because we have to reproduce the failure before we chase it. A shop that has been diagnosing your rig for two weeks has a scheduling problem, not a diagnostic problem.
2. Roof reseal and seam work (1 to 3 days)
Stripping old lap sealant, prepping, and resealing every penetration is a one to two day job. The third day is cure time, which runs longer in cold weather. Pricing is on the roof repair cost page.
3. Full roof replacement (5 to 15 days)
Stripping the membrane, pulling every rooftop component, replacing soft decking, laying new TPO or EPDM and resealing is a solid week minimum. Add days when the decking is worse than it looked. Rot in the walls under the roof edge pushes it to three weeks or more.
4. Slide-out mechanism repair (3 to 10 days)
A seal replacement or re-sync is two or three days. A motor or hydraulic cylinder is closer to a week, and most of that week is the part. A full rebuild where the slide comes out of the wall is two weeks and up. Older Lippert and Power Gear components are not sitting on a shelf anywhere. See the slide-out repair guide.
5. Water heater repair or replacement (1 to 3 days)
Element, thermostat or gas valve work is usually a single day. A tank swap is one to two days if the replacement is a current model. A discontinued Atwood means fitting a modern replacement, which adds a week.
6. Refrigerator repair or replacement (2 days to 6 weeks)
The widest range on the list, and it is entirely about the part. A control board or heating element on a Norcold or Dometic absorption fridge is two or three days. Cooling units have been scarce for years and a four to six week wait is normal.
7. Generator service and repair (1 to 5 days)
Annual service on an Onan is same day or next day. A carb rebuild is two days, a voltage regulator or stator issue three to five, full replacement about a week. Details on the generator service page.
8. Awning repair or replacement (1 to 5 days)
Fabric on a manual awning is one day. Power motors and arms run two to three days. Full assembly replacement is closer to five, because it has to be ordered in the right length and color and awning stock changes every model year.
9. Black tank and plumbing work (1 to 5 days)
Valve replacements, sensor cleaning and pump swaps are one to two days. A cracked tank means dropping the underbelly and sometimes cutting framing, which is three to five days.
10. Electrical diagnosis and repair (2 to 10 days)
Inverter, converter or transfer switch replacement is two to three days. Chasing a fault inside a wall or under a floor is where electrical gets long, and there is no shortcut. We open access panels from most likely to least likely and it takes what it takes.
11. Sidewall delamination (2 to 6 weeks)
Delamination is not cosmetic. The bubbling means the bond between the fiberglass skin and the substrate failed, usually because water got in. Localized sections take two to three weeks with cure time between stages. Full panel work is six weeks and up.
12. Collision and hail body work (3 to 10 weeks)
Body timelines are driven by the insurance carrier, not by us. Adjuster inspection, estimate approval, supplemental approval when we open it up and find more, then panel and paint availability. The physical work on a moderate hail claim might be two weeks. The claim process parks the rig for a month.

Why RVs sit at dealerships for months
The usual answer online is that dealers are lazy. That is not it. The reasons are structural.
Warranty authorization comes first. A dealer cannot order a warranty part or start warranty labor until the manufacturer approves the claim. In the IDS data, 42 percent of open work orders at the average dealership were waiting on a warranty resolution. That queue lives inside the manufacturer’s warranty department, and the dealer has almost no leverage over it.
Manufacturers pay less for warranty labor than you do. A shop choosing between a cash job at full rate and a warranty job at a discounted flat rate has an obvious incentive. That is how warranty reimbursement works across the whole vehicle industry, and it means warranty work drifts down the pile.
Dealers prioritize units they sold. Most large dealerships schedule their own buyers first. If you bought elsewhere, you are behind their customers before your paperwork is written.
Parts are the real constraint, not labor hours. There are more RV brands than car brands, each running dozens of floorplans that change yearly. An odd-sized window, a trim piece, a discontinued cooling unit, a slide motor from a 2011 build. A shop can have three technicians standing around and still not finish your rig because one bracket is three weeks out. Out-of-stock work orders averaged 54.3 days against an overall average of 30.6.
There are not enough technicians. North of 11 million RVs are on the road, roughly double twenty years ago, and the technician workforce has not grown with it. Large dealerships routinely carry over a hundred open work orders against a limited number of bays.
Nobody chases your part unless you do. Parts that were supposedly ordered sometimes were not. Owners who call the manufacturer and ask for shipping confirmation regularly find the order was never placed.
What you can do to shorten the wait
Approve the diagnostic immediately. Nothing gets ordered until we know what is wrong. Every day you sit on that authorization is a day added to the front of the job.
Decide fast on warranty versus paying. This is the biggest lever you control. On a $600 repair with a $200 deductible and a three week authorization queue, paying cash is often the better deal. We will tell you honestly which way the math goes.
Be reachable. When we open a wall and find rot, we stop and call. If we cannot reach you for four days, your rig sits open for four days. Tell us your approval ceiling up front so small additions do not stall the job.
Bring it in the off season. A job that takes ten days in June takes five in November. Same work, same crew, different queue.
Know your model, year, floorplan and serial numbers. Half of parts-ordering delay is confirming which version of a component your rig has. Send photos of the data plates with your first message and we can often have the part moving on day one.
Colorado seasonality and why it matters
The Front Range camping window runs roughly May through September. That compressed season drives shop scheduling here.
The spring rush is brutal. Every owner between Fort Collins and Colorado Springs de-winterizes in the same three weeks, pressurizes a water system that has sat since October, and finds the same problems at the same time. Every shop catches that wave at once. Booking six weeks out in April is normal, before any parts wait.
Then hail hits. Colorado’s severe hail window runs April through September but concentrates hard from mid-May through late June, and the Front Range corridor takes the worst of it. One storm can put dozens of damaged rigs into the same body shops in an afternoon, all going through insurance at once.
Fall and winter are the smart time to book. October through March we have bay space, parts have time to arrive without costing you a trip, and nothing competes with your job. If you have a roof reseal, slide service or generator overhaul that is not stopping you from camping right now, book it in the off season. Metro owners can start at the Denver RV repair page.

Frequently asked questions
How long does the average RV repair take?
Industry-wide the 2025 average was 30.6 days from work order open to close, per dealership data tracked by IDS. That includes long parts waits and warranty queues. Actual hands-on labor for most single-issue repairs is one to five days.
Why is my RV still at the dealership after two months?
Almost always one of two things: the manufacturer has not authorized the warranty claim, or a part is on backorder. Call the manufacturer directly and ask for the order confirmation and tracking.
Can you guarantee a completion date?
No, and be careful with any shop that does. We give a realistic range and tell you the moment a part becomes the constraint.
Is it faster to pay out of pocket than use my warranty?
Often yes on smaller jobs. Approvals add days to weeks before a part can even be ordered, so under about a thousand dollars the deductible plus the wait usually makes cash the better choice. On a slide rebuild or a roof, use the coverage.
What is the fastest time of year to get RV work done in Colorado?
October through March. Bay space is open, the de-winterization wave has not started, and hail season is over.
Do you work on my rig the entire time it is in your shop?
No shop does, and any shop claiming otherwise is not being straight with you. Rigs waiting on a part or on your approval are parked. What matters is that active jobs move continuously and parked jobs are parked for a reason we can explain.
Which repairs have the longest waits right now?
Absorption refrigerator cooling units and slide mechanism components for older rigs. Discontinued appliances on anything older than about fifteen years are the other common one.
