50 Things I Wish I'd Known Before My First RV Trip

The step light. That's what drained the chassis battery on my first RV trip and left me in a Walmart parking lot outside Harrisonburg, Virginia at 6am. Forty-five minutes later, a retired couple in a diesel pusher jumped me with a smile and said they'd done the same thing in their first year. I've been building this list ever since — 50 things from six years of mistakes, close calls, and campfire conversations from the Shenandoah Valley to the high desert outside Moab.

The Pre-Departure Walk-Around (Do This Twice)

Check all fluid levels before every trip — engine oil, transmission fluid, coolant, brake fluid, and windshield washer fluid. Test all exterior lights: running lights, brake lights, turn signals. Tires are where most first-timers underinvest; check pressure and tread depth on every tire including the spare, and look for sidewall cracking if the rig has been sitting in storage. Make sure your generator starts and runs for a full five minutes before you load anything.

The water system bites new owners more than any other system. Test your water pump, run it for 30 seconds, then get underneath and eyeball every connection. If you have slide-outs, cycle them before you load — a slide that binds at home is infinitely easier to handle than one that binds in the dark at your campsite. Check battery bank voltage; 12.4V or below on a 12V system means you're starting depleted.

Propane is the other one people rush. Fill your tanks before departure, not "somewhere on the way." Test your stove burners, water heater, and furnace at home. A furnace that won't ignite at 2am in November outside Moab is a rough discovery — give yourself the time to diagnose it in your own driveway.

Pack Like You're Moving Into a Very Small Apartment

Bedding and pillows for every sleeper — don't assume the RV comes stocked, even on rentals. Two bath towels per person, a set of kitchen towels, and a couple of rags for spills. A solid first aid kit lives under the dinette in every rig I've owned; the REI Backpacker kit is compact enough to fit in any cabinet. Flashlights and a headlamp with fresh batteries — campground power pedestals trip breakers at inconvenient hours.

RV-rated toilet paper is non-negotiable. Camco's RV toilet paper dissolves properly in your black tank; regular TP doesn't, and a clogged black tank on day two of a seven-day trip reorders your priorities fast. Bring all your prescription medications plus a basic OTC kit: ibuprofen, antihistamines, antacid, and something for stomach issues. The mistake I see most new RVers make is treating the medicine cabinet like they're packing a day bag.

In the kitchen, you need a sharp knife, cutting board, can opener, coffee setup (a pour-over cone takes up almost no space), and one good skillet. Paper plates are perfectly fine for your first trip. Add dish soap, a sponge, and a small broom — that broom earns its space within 48 hours of your first dirt road.

Arrival Day: Walk the Site Before You Back In

Don't pull in and immediately start backing. Walk the entire site first: locate the power pedestal and note whether it's 30 or 50-amp, find the sewer connection, check for low-hanging branches and unlevel ground. Many first-timers skip this and discover mid-back-in that the pedestal is on the wrong side of the rig. Five minutes of reconnaissance saves 30 minutes of repositioning.

Use a spotter — even experienced drivers do. If you're traveling solo, prop your phone on a camp chair at the rear of the site. Most established campgrounds, from KOA to state park systems, have enough clearance that you'll be fine with patience. Quiet hours vary by campground — many run 10pm to 7am, but some state park systems push to 8am and a few National Forest sites have none at all; ask at check-in rather than guessing.

Keep your footprint inside your site boundaries. Keep dogs leashed and clean up immediately. RV communities are genuinely some of the most helpful groups of people I've encountered — the connections we've made at campgrounds from Virginia's Shenandoah to Joshua Tree are still in our contact list years later. Give that culture some credit and it gives back.

The Gear Nobody Mentions Until You Need It

Know where your fire extinguisher is, and verify the gauge needle sits in the green. Test your smoke detector and carbon monoxide detector before every trip — CO from a faulty furnace gives no warning. Carry a basic tool kit: screwdrivers, pliers, adjustable wrench, Valterra leveling blocks, a roll of Flex Tape, and zip ties. Those six items have resolved 90% of the roadside issues I've run into.

Road flares or a set of reflective triangles ride in the side bay of every rig we've owned. Know how to change a tire on your specific rig — not just conceptually, but where the jack points go and whether your lug wrench actually fits your lugs. A Good Sam or AAA RV roadside membership runs about $100 a year and covers tows that run $400-plus without it. On your first few trips, that membership isn't optional.

The Weight Problem Nobody Warned Me About

Your rig has a Gross Vehicle Weight Rating (GVWR). Exceed it and you're affecting handling, risking a tire blowout, and potentially voiding roadside coverage. Most first-time RVers overpack by 15–20% without realizing it. Find a certified CAT Scale — most Flying J and Pilot locations have one — weigh your loaded rig before your first long haul; it costs under $15, takes ten minutes, and as of spring 2026 the CAT Scale app stores your results, which is useful for insurance purposes too.

The rule from our first season still holds: pack roughly half of what you think you need and budget 20% more than you planned. You'll buy what you forgot along the way — that's half the point. October in the Shenandoah or shoulder season in the Southwest, campground stores stock more than you'd expect.

One more thing from six years on the road: be patient with yourself on trip one. You will forget something, make a backing mistake, and misread a hookup — every seasoned RVer in that campground has done all of it. The learning curve is shorter than it looks from your driveway, and the community is more forgiving than you'd expect from strangers. — the RVMapper team, on the road since 2019
