The Hidden Costs Of Full-Time RV Living Nobody Mentions

My first week full-time was in a Walmart parking lot in Barstow, California, in July, and the temperature inside my rig hit 104 degrees because I didn’t yet understand that my roof AC unit needed 30-amp shore power to run properly and I was plugged into a 15-amp extension cord I’d bought at Home Depot like an absolute rookie. I ate warm string cheese and watched a YouTube video about amperage on my phone, sweating through my shirt, wondering what I had done.

That was eight years ago. I’ve since logged somewhere around 140,000 miles across 41 states, lived through two major engine failures, one flooded bathroom, and a refrigerator that died in New Mexico with $300 worth of groceries inside. I’m not telling you those stories to scare you off. I’m telling you because everything I know, I learned the hard way, and I’d rather you didn’t have to.

Here’s what I actually wish someone had told me before I handed over the keys to my apartment.

The Money Math Is Probably Wrong, and You Need to Fix It Before You Leave

Everyone does the napkin math before going full-time. Monthly RV payment plus campground fees plus fuel, subtract rent, comes out ahead. Done.

That math is almost always wrong.

The part people miss is what I’d call the “first year tax,” which is the cluster of unexpected costs that hits you in months one through twelve before you’ve figured out your systems. I spent roughly $7,400 in unplanned expenses my first year: a new water pump ($340 installed), two blown tires on the toad (I was driving a Jeep Cherokee behind a Class A, $680 total), a warranty repair that wasn’t covered because I hadn’t registered the extended warranty within 30 days like I was supposed to, a propane regulator that crapped out in November in Wyoming, and about $1,200 in campground fees I wouldn’t have paid if I’d known about Harvest Hosts, Boondockers Welcome, and how to actually use BLM land.

Set aside a minimum of $5,000 in a dedicated RV emergency fund before you go. Not your general savings. A dedicated account. And honestly, $8,000 is better. I’ve watched so many people go full-time on a thin margin and get stranded by a transmission repair that any experienced full-timer would shrug off as “just a thing that happens.”

On the campground side: current rates (as of July 2026) at full-hookup parks in popular areas like Sedona, Asheville, or coastal Maine are running $55 to $85 per night. If you’re planning to stay put for a month in any of those spots, that’s $1,650 to $2,550 just for the pad. I know people who thought they’d be “free camping” most of the time and ended up spending $1,100 a month on parks because they underestimated how often they’d want electricity.

Your Rig Will Break in the Worst Place at the Worst Time. Here’s the Only Useful Thing to Do About It.

I had a reader named Paul from Columbus email me last spring about a slide-out that jammed shut in a campground outside Amarillo, TX, right before a cold front moved in. He spent three days waiting for a mobile tech because he didn’t know what warranty coverage he actually had or who to call.

What most people don’t realize is that RV manufacturers’ warranties and extended warranties often have massive geographic gaps in service network coverage. Coach-Net and Good Sam Roadside are the two dominant services most people end up with, and in my experience, Coach-Net’s mobile tech network is genuinely better in rural areas. I’ve used both. Coach-Net got a tech to me in western Montana in four hours. Good Sam took eleven, and the guy who showed up wasn’t sure what a Cummins Onan generator was.

Beyond roadside, learn to fix basic things yourself before you go. I’m not saying you need to become a diesel mechanic. But you should be able to: replace a water pump, reseal a window, reset a tripped breaker on your converter, and bleed air from propane lines after a tank swap. YouTube’s “RV Repair Club” channel is legitimately good for this. I learned how to replace my water heater anode rod from a 12-minute video, which saved me a $200 service call.

A practical scenario, worked out: Paul’s slide-out problem → He eventually got a mobile tech who charged $385 labor plus a $90 part → Total cost $475, but he lost three days of his planned route and paid $210 in unexpected campground fees while waiting. If he’d had the slide-out’s basic manual operation procedure written in his phone notes (usually a manual crank or hex bolt bypass), he could have gotten the slide in himself in 20 minutes and kept moving.

Mail, Domicile, and Health Insurance: Nobody Warns You Enough About This Triangle

7 Things We Wish We Knew BEFORE Starting RV Life FULL-TIME (1 month on the road) · Lloyd & Mandy on YouTube

Three things you can’t ignore, all connected, all annoying.

Domicile is your legal state of residence, and it affects your taxes, your vehicle registration costs, your driver’s license, and critically, your health insurance options. The three most popular domicile states for full-timers are South Dakota, Texas, and Florida, because they have no state income tax. South Dakota is the easiest to establish (you can do it in a day in Sioux Falls through companies like America’s Mailbox). I chose South Dakota in year two after my accountant pointed out I was still paying California income tax for no reason.

Mail forwarding services (America’s Mailbox, Escapees Mail Service, and St. Brendan’s Isle are the main three) typically run $150 to $200 per year for basic service, and you’ll pay per scan or per forward on top of that. Budget $30 to $50 per month for mail-related costs if you get any volume. It adds up.

Health insurance is where this gets genuinely hard. If you’re under 65 and not covered through a remote employer, your options are ACA marketplace plans, which are often cheaper than you’d expect if your income is modest, or a health-sharing ministry, which is not insurance but can work for generally healthy people who want catastrophic coverage. I’m not going to pretend this is solved. It’s complicated, the costs vary enormously by state and income, and I’ve seen people make perfectly reasonable choices that backfired. I use an ACA bronze plan with a high deductible paired with a solid HSA, currently running me about $310 per month in 2026. That’s workable. But I’d talk to an independent insurance broker who works specifically with nomads before you commit to anything. Some of them specialize in this.

Solar and Batteries: The Upgrade That Actually Changed My Life

I resisted going solar for two full years because I thought it was a luxury for people who had more money than sense. I was wrong, and it cost me probably $4,000 in campground fees over those two years because I kept paying for hookups I didn’t need.

My current setup: 400 watts of Renogy solar panels on the roof, a Victron SmartSolar MPPT charge controller ($189 on Amazon, well worth it), and two 100Ah Battle Born lithium batteries. The whole system, which I installed myself over a long weekend with help from Will Prowse’s YouTube channel, cost me about $2,100 in parts. I can now run my laptop, charge devices, power LED lighting, and run the fantastic fan for four to five days without plugging in. I can’t run the AC off solar alone, and anyone who tells you 200 watts will run your air conditioner is either lying or selling something.

A battery monitor is non-negotiable. The Victron BMV-712 ($89 on Amazon, affiliate link) was one of the smartest $89 purchases I’ve made. Without one, you’re guessing at your battery state and usually guessing wrong.

Worked example on solar ROI: My campground costs in year two (pre-solar) averaged $780/month. After installing my solar setup, I boondocked an average of 18 nights per month instead of 6, dropping my campground spend to roughly $420/month. That’s $360/month saved, meaning my $2,100 system paid for itself in under six months.

The Psychological Stuff Nobody Posts on Instagram

Here’s the part that catches people off guard more than any mechanical failure: the loneliness is real, it comes in waves, and it doesn’t mean you made the wrong choice.

The first few months feel like vacation. Then reality sets in. You miss people. Not in an abstract way, in a specific “I just want to have dinner with someone who knows me” way. I went through a pretty rough patch around month five, and I almost quit. I didn’t, partly because I’d burned my bridges and partly because a guy named Dan at a campground in Taos sat down next to my campfire uninvited and ended up becoming one of my closest friends.

What I’d tell you is this: build community deliberately, don’t wait for it to happen. The Escapees RV Club has rallies worth going to. The Facebook group “RVillage” was useful for a while; it’s quieter now but still active. Apps like The Dyrt help you find where other full-timers are congregating. And show up at campfire hours. Just show up.

One more thing I got badly wrong at first: expecting my productivity to go up because I’d “freed myself” from a traditional life. What actually happened is that motion itself eats time. Moving the rig, setting up camp, breaking down camp, finding dump stations, figuring out cell signal, doing rig maintenance: on heavy travel weeks I’d lose ten hours to logistics I hadn’t budgeted for. If you work remotely, plan to stay somewhere for at least two to three weeks at a time, not two to three days.
