Summer RV Trip Checklist: Everything Before You Hit the Road

The first summer we hit the road in our RV, we forgot the water pressure regulator, left the bathroom vent open (which flooded the bathroom when it rained on the highway), and realized 200 miles from home that we had not turned on the propane before leaving, which meant no fridge cooling for six hours of driving. None of these were catastrophic individually, but together they turned our first day into a series of small frustrations that set the tone for the whole trip.

Since then, Emily and I have developed a pre-trip checklist that we run through before every departure. It takes about 45 minutes to complete, but it eliminates the kind of surprises that ruin the first day of a trip. We have refined this checklist over four years and hundreds of travel days, and it now covers every system and every common mistake we have either made ourselves or watched other campers make.

Print this out, laminate it, and hang it in your RV. It will change how you start every trip. For a broader look at planning multi-day adventures, our multi-week road trip planning guide covers the strategic side of trip preparation.

Two Weeks Before Departure

Starting preparation two weeks out gives you time to order parts, schedule repairs, and handle anything unexpected without rushing.

Mechanical and Systems Check

Engine oil and filter: If you are within 500 miles of your next oil change, do it now. It is much easier in your driveway than at a random oil change shop on the road.

Coolant level: Check the overflow tank when the engine is cold. Top off if low. Summer driving, especially towing, puts maximum stress on your cooling system. If your coolant is more than two years old or 30,000 miles, consider a full flush before a summer trip.

Transmission fluid: Check level and color. Fresh transmission fluid is bright red or pink. Dark brown or burnt-smelling fluid needs attention, especially before towing in hot weather. Transmission failure from overheated, degraded fluid is one of the most expensive roadside emergencies you can face.

Brake inspection: Check brake pad thickness (or have a shop check them). Towing generates significantly more heat and wear on brakes than normal driving. If pads are below 4mm, replace them before the trip. Also check brake fluid level.

Tire inspection: Check all tires (including the spare) for proper inflation, tread depth, and signs of dry rot or cracking on the sidewalls. Tires older than 5 to 7 years should be replaced regardless of tread depth because the rubber compound degrades. This applies to both tow vehicle and trailer tires. Our common packing mistakes article covers why tire gauges belong in your essential toolkit.

Battery check: Test your vehicle battery and your RV house batteries. A battery load test costs about $20 at an auto parts store and tells you whether the battery will handle the demands of a summer trip. Our battery guide covers maintenance specifics for both lithium and lead-acid setups.

Campground and Route Planning

Reservations confirmed: Double-check every campground reservation. Print confirmation numbers or save them to your phone. Summer is peak season, and many campgrounds overbook or have strict cancellation policies. Call to confirm if your reservation was made months ago.

Route reviewed: Check your planned route for construction, road closures, and low-clearance bridges. RV-specific GPS apps and routing tools account for vehicle height and weight restrictions that standard navigation ignores. See our must-have RV apps guide for the best route-planning tools.

Dump station locations: Identify dump stations along your route and at or near each campground. Running out of black tank capacity with no dump station nearby is a problem you do not want to solve on the fly. Our black tank guide covers managing tank capacity for extended trips.

Fuel stops planned: If you are towing or driving a motorhome, your fuel range is shorter than you think. Plan fuel stops before your tank hits a quarter. Gas stations with RV-accessible fuel islands (long pull-through lanes) are not everywhere, so know where they are along your route.

Three Days Before Departure

Provisions and Supplies

Grocery shopping: Buy non-perishable food items three days before. Perishable items the day before. Plan meals for at least the first three days so you are not scrambling to find a grocery store on day one. Our meal prep guide has a system for planning camping meals efficiently.

Water supply: Fill your fresh water tank if you are heading somewhere without reliable water hookups. Bring a water filter if you are not sure about water quality at your destination. A portable water filter like a Sawyer or Berkey system costs $30 to $80 and gives you peace of mind at any water source. Our water system guide covers filtration options in detail.

Propane check: Check propane levels in all tanks. Top off before you leave. Running out of propane on a Sunday evening in a small town is a frustrating experience. We keep our tanks at least half full at all times during travel season. Our propane safety guide covers system checks and tank management.

First aid kit: Verify your first aid kit is complete and nothing has expired. Restock any items you used since your last trip. Add sunscreen (SPF 30 minimum), insect repellent, and any prescription medications. Summer-specific additions include aloe vera for sunburn and electrolyte packets for dehydration.

Pet supplies (if applicable): Extra food, water bowls, leash, vet records, flea and tick prevention, and any medications. Summer heat creates specific risks for pets, which our camping with dogs guide addresses in detail.

Interior Preparation

Deep clean: A quick vacuum, counter wipe, and bathroom cleaning before a trip means you arrive at your destination in a clean, welcoming space rather than adding "clean the RV" to your first-day to-do list.

Bedding: Fresh sheets and pillowcases. Pack extra blankets even in summer because some mountain and desert locations get surprisingly cold at night.

Secure loose items: Walk through the RV and make sure everything is secured for travel. Cabinet contents shift during driving. Anything on a counter will end up on the floor. Heavy items on upper shelves are missiles during a sudden stop. Use bungee cords, shelf bars, and non-slip mats to keep everything in place.

Day Before Departure

Exterior Check

Roof inspection: Climb up and check all seams, sealant around vents, skylights, and air conditioning units. Look for cracks, gaps, or areas where sealant has pulled away. Reseal any questionable spots with appropriate RV sealant (Dicor self-leveling for flat roof surfaces, non-leveling for vertical surfaces). A roof leak discovered on the road means water damage to your interior, and summer rainstorms can be intense and sudden.

Awning condition: Extend the awning and check for tears, mold, or mechanical issues. Make sure it extends and retracts smoothly. A malfunctioning awning is either useless or dangerous depending on the failure mode. We cover thorough awning maintenance in our dedicated guide, and it applies directly here.

Window and door seals: Check all window and door seals for gaps or deterioration. Close each window and door and look for daylight around the edges. Deteriorated seals let in rain, dust, and insects. Replacement seal material is available at RV supply stores and is easy to install.

Exterior lights: Test all running lights, brake lights, turn signals, and any auxiliary lights. Have someone stand behind the vehicle while you operate each light from inside. Replace any burned-out bulbs before departure. Traveling with non-functional lights is illegal and dangerous.

Systems Test

Run the refrigerator: Turn on the fridge at least 12 hours before departure so it reaches temperature before you load perishable food. An RV fridge takes significantly longer to cool down than a residential one. If your fridge runs on propane, verify propane operation. If electric, confirm shore power or generator operation.

Water heater test: Run the water heater to verify it ignites and heats properly. Test on both propane and electric modes if your unit has both. Finding a water heater problem at home is much better than discovering it at the campsite.

AC test: Run the air conditioner for 15 minutes and verify it cools effectively. Listen for unusual noises. Check that the air filters are clean. Summer heat makes AC essential, not optional, and a broken AC unit found at the campsite means a miserable trip or an emergency repair bill.

Slide-outs (if applicable): Extend and retract all slide-outs. Check the seals around each slide for gaps or damage. Make sure the mechanism operates smoothly without grinding or hesitation.

Departure Morning

Interior Walk-Through

Secure everything one more time. Open every cabinet and drawer. Make sure the fridge and freezer doors are latched. The bathroom door should be secured open so it does not swing and bang during travel. Confirm the stove burners are off and propane appliance valves are in the correct position for travel.

Retract all slide-outs if you extended them at home. Check each one from outside to verify it is fully retracted and the seals are properly seated.

Close all windows and vents. This is the one that got us on our first trip, we left the bathroom vent cracked open and it rained. Walk through every room and verify every window and vent is closed and latched. This includes the fantastic fan covers and any roof vent openings.

TV antenna down. If you have a roof-mounted antenna, retract it. Driving with the antenna up is a quick way to destroy it on the first low-hanging branch or drive-through you encounter.

Exterior Walk-Around

Utility disconnections: Disconnect and stow shore power cable, water hose, and sewer hose. Make sure the water heater bypass is set correctly for travel. Close all external compartment doors and verify they are latched.

Awning retracted: Confirm the awning is fully retracted and secured. Check that awning arms are locked in the travel position.

Wheel chocks removed: Pull wheel chocks and leveling blocks. This sounds obvious, but driving away with leveling blocks under your tires damages both the blocks and potentially the jacks.

Steps retracted: Electric steps should auto-retract when you start the engine, but verify visually. Manual steps must be folded up and secured. Driving with steps extended tears them off at the first curb or steep driveway transition.

Hitch and towing (if applicable): Run through the complete towing safety checklist: coupler locked, safety chains crossed, breakaway cable connected, electrical plug secured, trailer brakes tested. We cover this in detail in our towing guide, and every item matters.

Essential Summer-Specific Items

Beyond the standard RV packing list (which our packing list guide covers comprehensively), summer trips require some specific additions:

Sun protection: Reflective windshield cover, reflective window inserts for all windows, sunscreen, hats, and sunglasses. The reflective covers make a 10 to 15 degree difference in interior temperature when parked in the sun.

Cooling gear: Extra portable fans, a misting bottle, cooling towels, and plenty of ice. Even with good AC, these items help during setup and breakdown when the AC is not running.

Hydration supplies: More water than you think you need. A good rule is one gallon per person per day for drinking, plus whatever you need for cooking and cleaning. In hot weather, dehydration is a real risk, especially for kids and older adults.

Bug protection: Screen for the entrance door, citronella candles, bug spray, and a fly swatter. Summer camping without bug protection means spending all your outdoor time swatting instead of relaxing.

Shade structures: A pop-up canopy or extra tarp provides shade at campsites where trees are sparse. The awning helps, but additional shade for the campfire area or cooking space makes a huge difference in comfort.

The 10-Minute Post-Arrival Checklist

When you arrive at your campsite, before you start relaxing, run through these items quickly:

Level the RV. Use leveling blocks, jacks, or whatever system you have. An unlevel RV means the fridge does not work efficiently (especially propane fridges, which rely on gravity for cooling), doors swing open or closed on their own, and sleeping on an angle gets old fast.

Hook up utilities. Shore power first (using a surge protector), then water (with a pressure regulator), then sewer if available. Our campground hookup guide walks through each connection in detail.

Extend slide-outs and awning. Make sure you have clearance for both before extending. Check for tree branches above the awning and obstructions around the slide-out path.

Walk the site. Check for hazards: low-hanging branches, uneven ground, fire ring condition, and the location of your neighbors. Set up your outdoor space, chairs, table, mat, and lights, so everything is ready for an enjoyable evening.

A good checklist makes the difference between a trip that starts with stress and one that starts with confidence. Every item on this list exists because we either forgot it and paid the price, or we watched someone else forget it and learned from their mistake. Take the 45 minutes before you leave. Check everything. Then hit the road knowing you are ready for whatever summer throws at you.

Happy trails, Mike & Emily
