Ask what an RV renovation costs and you get answers from a few hundred dollars to more than the RV is worth. Both ends are real. The spread is not because some people shop better. It is because the word covers three different projects, and the vehicle decides which one you are doing.
Every figure on this page is in US dollars, from US sources, and most of it is what other people actually spent rather than what a calculator says. If you are in Australia, the UK or Europe, use the proportions, not the prices. Your sheet goods, your batteries and your labor are all priced differently, and the plywood is a different product, which I come back to below.
Three projects that share a name
A refresh. Paint, hardware, fabric, lighting, maybe a floating floor over a sound subfloor. Nothing structural, nothing inside a wall. This is the project in most of the before-and-after photos, and it is cheap because it is mostly your time.
A working remodel. The refresh plus at least one system: a rewire, a battery bank, new cabinetry, plumbing. The materials are still modest. The cost is in the parts you cannot see and the hours you cannot skip.
A structural repair with a renovation on the end. Water got in, and the floor, a wall or the roof deck has to come apart before any of the above can start. This is the project that produces the five figure totals, and nobody plans it. They discover it.
The whole reason to inspect before you budget, as laid out in where to start on a camper renovation, is that the inspection tells you which of these three you have bought. Budgeting before that is guessing.
What the real DIY totals look like
The refresh numbers from people who kept receipts sit lower than most first-timers expect.
Travels with Ted collected nine owner write-ups. One family repainted, replaced furniture and built custom bunks in a 30 ft fifth wheel and expected to land just over $1,000 in total. Another paid $1,700 to have the painting done on a newer 40 ft fifth wheel and did the cosmetic changes themselves. RV Inspiration’s own round-up puts most DIY remodels under $5,000 when there is no major damage to repair, and it features a 25 year old fifth wheel redone for under $2,000 and a Class C done for around $500 with paint, sewn curtains and vinyl over the carpet. All Things With Purpose, who have renovated and flipped a run of older campers, describe renovations from about $100 to $2,000 on campers bought for $500 to $6,000, with a 1990s motorhome budgeted at roughly $2,000 including tires and mechanical work.
Notice what those totals have in common. None of them include a structural repair, a battery bank or professional labor. Add any one of those and the number changes category.
The line item that decides everything: water
Water damage is where the budget is won or lost, and the repair trade is unusually consistent about the shape of it.
BossBros RV, a mobile repair outfit, breaks the cost down by stage. A soft spot under about 2 sq ft with a single entry point resealed runs $400 to $800. A larger floor section or a wall panel runs $1,500 to $3,500. Full floor, roof decking or slide-out structure runs $5,000 to $8,000 or more. TJs RV, a repair shop, gives the same shape without the hard numbers: several hundred for a small soft spot caught early, a thousand to several thousand when subfloor sections come out, and beyond that when rot reaches framing, insulation or walls.
Two things in those write-ups matter more than the figures.
Access costs more than the repair. BossBros put it plainly: getting to a rotted joist means removing cabinetry, flooring and paneling, and that labor often exceeds the repair itself. Which is exactly why the order of work on this site always puts water first. A repair found after the new floor is down is the same repair plus the new floor.
Delay multiplies it. Both shops name the age of the leak as the biggest single cost driver. BossBros’ own example is a $400 repair becoming a $2,000 repair after six months left alone. Delamination, where the outer skin lets go of the wall, is the expensive end of that curve, and TJs RV notes that once those repairs climb into the thousands it is worth comparing the number with what the RV is worth.
If you are still deciding whether to buy, this is the section that justifies paying for an inspection.
The roof, which is the cheapest insurance on the list
Resealing the roof is the job that stops the section above from happening, and it is cheap compared with everything it prevents.
The reseal guides put DIY materials in the low hundreds of dollars, with Jeffsetter’s figure at around $500 once tools are included. Professional resealing quotes in the same guides run from several hundred dollars to about $2,000 depending on the size of the rig and whether minor repairs are needed first. Jeffsetter also gives the interval: a thorough reseal every three to five years, sooner in hard sun.
If the budget only stretches to one exterior job, this is it.
Paint, which is mostly labor
Painting cabinets is the single biggest visual change per dollar in an RV, and it is also the clearest example of how labor moves the number.
RV Reports’ cost breakdown for a travel trailer or Class C galley puts DIY materials at $140 to $440 without a sprayer: consumables, a bonding primer, a cabinet grade enamel and rollers. The same write-up prices mobile painters at $800 to $2,500 for doors and galley done in place, and shop-sprayed doors at $1,500 to $4,000 and up. RV Inspiration’s round-up includes a couple who spent around $8,000 having cabinets professionally painted.
That is the same job at roughly a twenty-fold spread, and the difference is who holds the roller. If you do it yourself, the money goes on primer, not paint. How to paint RV cabinets covers why the primer is the part you cannot economise on.
Flooring, where the material is not the cost
An RV floor is small, so the plank is rarely the expensive part. HomeGuide puts luxury vinyl plank materials at roughly $1.50 to $7 per sq ft, and even a large fifth wheel does not have many hundreds of square feet of walkable floor. RV Inspiration’s range for replacing an RV floor, a few hundred to a few thousand dollars, is wide precisely because the top end includes subfloor repair.
So the flooring budget is really two lines. The plank, which you can price in ten minutes. And the subfloor, which you cannot price until you have walked the floor and probed the soft spots. RV flooring covers what to check underneath before you buy anything.
The 12 volt side, where DIY saves the most
This is the system where the gap between doing it and paying for it is widest, and where the parts people forget add up.
LiTime’s upgrade breakdown puts a weekend system at $1,000 to $3,000 and a high capacity setup for extended off-grid use at $5,000 to $10,000 or more, with the lithium battery itself at 40 to 50 percent of the total. Solar RV Tips gives a similar spread for a complete solar system: about $640 to $4,500 DIY against $1,200 to $7,500 installed. Both agree on where the money goes: the battery bank first, everything else a long way second.
The parts that catch people are the small ones. LiTime budgets $100 to $300 for cables, fuses and terminal lugs on top of the battery, and $500 to $1,500 for labor if you do not do it yourself. A lithium compatible converter and a DC to DC charger for charging off the alternator are separate purchases that rarely appear in the headline price of a battery. None of it is expensive on its own. All of it is a surprise if it was not on the list.
Two things worth saying from having done this.
Do not save money on the cable and lugs. A marginal crimp or an undersized run is the cheapest part of the system and the most likely to cost you the rest of it. The DC wire size calculator will tell you what the run actually needs.
Size the bank before you price it. The battery is half the budget, so a bank sized by guesswork is the fastest way to overspend or to end up short. The battery bank calculator does the sum from what you actually run.
For a van build, the same system is the biggest single line by a distance. The Vansmith’s real-example breakdown puts a basic van electrical system at $3,000 to $5,000 and a full lithium and solar setup at $15,000 to $20,000, while The Van Conversion Guide’s budget build runs a low-cost system at around $500 and a high-end one at about $3,300. The gap between those two sources is itself the lesson: the electrical budget is set by how much battery you decide you need, not by the van.
Plywood, in both markets
I have not put a plywood price on this page, because sheet prices move with the timber market and vary by grade and merchant more than any other material here. What I can tell you is the number to get right, which is the sheet count.
The sheet is a different product in each market, so a materials list from a US build does not transfer. The US sheet is 4 ft x 8 ft, milled to 1220 x 2440 mm. AU and NZ merchants stock 2400 x 1200 mm, though some carry 2440 x 1220 mm as well. Continental EU stock is 2500 x 1250 mm. A cut list nested for the US sheet can need an extra sheet on the AU sheet, because the long side is 40 mm short, and one extra sheet of cabinet grade ply is real money.
| Where it goes | US stock | Actual | Metric stock | Actual |
|---|---|---|---|---|
| Cabinet sides, and anywhere a screw has to hold | 3/4 in ply | 18.26 mm | 18 mm ply | 18.00 mm |
| Shelves, dividers, general casework | 1/2 in ply | 11.91 mm | 12 mm ply | 12.00 mm |
Do not treat a pair as one item. US ply is named nominally and milled under that name. Metric ply is what the label says. Buy the sheet your merchant stocks, and price the job on that sheet. The cut list calculator nests your panels on your market’s sheet and gives you the count, which is the number you multiply by whatever your merchant is charging this month.
Paying someone
If the question is what a professional renovation costs, the answer starts where most DIY budgets end.
RV Inspiration’s piece on hiring a renovator quotes one shop starting at $25,000 in labor alone, before materials, with full gut renovations at $75,000 and up. The same piece gives a broader spread of about $15,000 for a small RV to $40,000 for a large one, supplies and labor included. The reason is the one RV Inspiration names directly: paint and flooring are the two largest, most labor-intensive jobs in any remodel, and they are also the two jobs most people can do themselves.
That is not an argument against hiring. It is an argument for hiring selectively. Pay for the structural repair, the welding, the propane test, or the roof if you are not steady on a ladder. Do the paint.
Two things to add to the total
A contingency. The Vansmith’s guidance is 15 to 20 percent set aside for hidden repairs, and the van build guides put the same figure at 10 to 20 percent for overruns and design changes. On an older RV I would sit at the top of that range, because the things that age out, tires, seals and wiring, are covered in old camper remodel and most of them do not show in the photos.
Resale, honestly. RV Inspiration’s take is that the old rule about renovations lowering resale value is out of date, because demand for renovated RVs has risen, but that a renovation still needs to be an upgrade in a neutral style rather than a downgrade in a personal one. The owner forums are more cautious. One RV Forum estimate is that a full restoration of an old rig lifts the value by only about a quarter of what the restoration cost. Treat that as the range: a good renovation of an old RV may recoup a fraction of its cost, and a renovation of a newer one is for you, not the next owner.
The order of spend
Money follows the order of work, because what buries what also decides what you cannot undo.
- The inspection. Free if you do it, a few hundred if you pay for one. It sets the budget.
- Water damage repaired and proven. The one line that can be anything from a tube of sealant to the largest number on the page.
- The roof resealed. Cheap, and it protects everything below it.
- Anything inside a wall or under a floor. Wiring, the battery bank, plumbing. Priced from the calculators, not from a kit’s headline number.
- Floor, then cabinets. Plank is cheap. Sheet count and subfloor are where the cost lives.
- Paint, fabric, hardware. The line with the best return per dollar, and the one to do last.
Where the rest of this goes
The pages that go with each line are the ones linked above: where to start for the inspection, RV flooring and painting RV cabinets for the two jobs that decide whether you are paying for labor, and old camper remodel for the age-related costs that catch people on anything with a few decades on it. For the 12 volt budget, the battery bank calculator and DC wire size calculator are where the two biggest electrical numbers come from.
