RV Maintenance Budget: What to Plan Annually

My third summer on the road, I blew $3,400 in a single month on repairs I hadn’t budgeted a dime for. New water pump, a slideout motor that decided to quit in 100-degree Arizona heat, and a set of tires that were technically “fine” until they weren’t. I’d been running lean because YouTube made full-time RV life look like it was mostly sunsets and coffee. Nobody talked about the $847 you hand to a mobile RV tech who shows up three hours late and smells like he drove through a McDonald’s on the way.

Here’s what I know now after eight years of this: maintenance costs are the number that breaks people. Not the rig payment, not campground fees. The repairs. Because unlike a house where you can limp along with a leaky faucet for six months, a broken rig is a broken home and often a broken schedule.

So let’s actually talk numbers.

The Honest Baseline Numbers

Most RV blogs throw out “$1,000-$2,000 a year” and call it done. That’s not wrong for a newer rig used recreationally a few weeks a year. It’s wildly optimistic for anyone living in their unit full-time or driving it across the country every season.

Here’s what I’ve tracked across my own ownership and from conversations with long-timers in the community:

These are full-time-use figures, not weekend-warrior numbers. Cut them roughly in half if you’re using your rig 60 days a year or fewer, and add 20-30% if your unit is more than 10 years old.

What most people don’t realize is that rig type matters less than age and usage intensity. A well-maintained 2021 Class A used part-time might cost you less than a 2019 travel trailer that’s been dragged to the coast every other weekend by someone who skips the roof seal inspection.

Breaking Down Where the Money Goes

Tires are the biggest one-time hit most people don’t plan for. A set of six ST-rated tires on a Class A runs $1,400-$2,200 installed, depending on size and brand. I run Michelin XPS Ribs on my Class A (currently around $285 each) because I watched a guy on I-40 outside Amarillo deal with a blowout that shredded his entire rear compartment. Good tires are not where you cheap out. Budget for replacement every 5-7 years regardless of tread depth, because UV degradation kills sidewalls before wear does.

Roof maintenance is chronic and sneaky. The eternal enemy of an RV is water intrusion, and it almost always comes from a failed sealant joint on the roof. I reseal my roof every single year, running a full tube of Dicor self-leveling lap sealant ($12-$15 per tube, I use about four) around every vent, skylight, and AC base. Takes me three hours on a Saturday. If you skip this for two or three years, you’re looking at potential decking replacement that runs $3,000-$8,000 depending on how far it spread.

Generator service, if you have one. Onan generators are the industry workhorse, and they need an oil change roughly every 100-150 hours of use. The oil and filter run maybe $40, but if you let it sit for a season without running it, the carb gums up. I’ve seen people spend $400-$700 on a carburetor service that could’ve been avoided by running the genny 30 minutes every month and adding Sta-Bil to the fuel.

Here’s the full breakdown by category as I’d actually budget it for a mid-2010s Class A gas pusher, full-time use:

That “miscellaneous” line is not padding. It’s always used. Every year something fails that wasn’t on the list.

The Full-Timer Math Is Different

Weekend warriors can get away with reactive maintenance. You notice a problem, you fix it before the next trip. Full-timers can’t do that. When you live in the thing, you’re running systems hard. AC runs 8-10 hours a day in summer. The water pump cycles dozens of times daily. The slideouts open and close every time you set up camp, sometimes twice a week.

I’ve seen full-timers average around $4,500-$6,000 annually on maintenance and repairs when they’re honest about it, and that’s not including upgrades or cosmetic work. One reader, Mark from Phoenix, tracked every receipt over 18 months and came out to $7,312 total, or roughly $4,875 annualized. His rig was a 2014 Tiffin Allegro, which is a quality coach. Older or lesser-built rigs can run higher.

The scenario that bites people hardest: first two years of full-timing, costs seem manageable because everything is still relatively new or recently inspected. Then year three hits and the fridge compressor goes ($800-$1,400), the AC needs a new capacitor and blower motor ($350), and the leveling system starts hunting for level and never quite finds it ($600-$1,200 for hydraulic system work). All in one summer.

I thought for years that my mechanical background would insulate me from big bills. It does help, a lot, but it doesn’t stop things from failing. It just cuts the labor cost, which is often 50-60% of what a shop charges.

What To Actually Do With These Numbers

Build two separate buckets. One is your maintenance budget, covering everything routine and semi-routine: oil changes, filter swaps, roof seals, tire rotation, generator service. Budget $1,500-$2,500 for that depending on your rig age and type. The second bucket is your emergency reserve, and it should sit at $5,000-$8,000 untouched. Not invested. Liquid. Sitting in a high-yield savings account where you can wire it to an RV repair shop in Flagstaff on a Tuesday afternoon without panic.

For protecting your electrical systems, a Progressive Industries EMS-HW50C hardwired surge protector is around $290 installed and has saved me from at least two sketchy campground power situations. The site may earn a commission on purchases like that, but I’d tell you the same thing either way because I’ve watched bad shore power kill inverters and damage appliances.

A quality water filter on your city water inlet, something like the Camco TastePURE inline filter at around $25, extends the life of your water pump and water heater by keeping sediment out. Replace the cartridge every 3-4 months if you’re full-timing. Small thing, genuinely extends component life.

As of August 2026, labor rates at RV repair shops run $120-$175/hour in most markets, with mobile techs sometimes higher because of their convenience factor. That’s up significantly from even three years ago. DIY capability, even basic stuff like replacing a water pump or resealing a roof vent, can save you $300-$600 per incident.
