A mid-season RV inspection should focus on tires, towing equipment, exterior seals, appliances, plumbing, and electrical connections. Checking these areas between trips helps you spot wear, leaks, and operating problems while there is still time to address them before your next departure.
Use this checklist alongside the maintenance schedules in your Keystone Owner’s Manual and component manuals. It supplements your regular pre-trip checks rather than replacing them.
Start with the components that carry your RV down the road.
Inspect each tire, including the spare, for:
Check pressure before driving, while the tires are cold. Do not release air from warm tires simply because their pressure has increased during travel.
Verify lug-nut torque using a torque wrench and the correct specifications and sequence for your wheels. Follow the required recheck schedule after wheel removal or installation. Keystone’s RV lug-nut torque guidance explains the importance of this maintenance task.
Also inspect the hitch, trailer wiring connection, breakaway cable, and safety chains where applicable. Address damaged or loose components before towing.
Your tow vehicle needs attention throughout camping season, especially after repeated trips or heavy towing.
Follow its manufacturer’s procedures for checking:
Confirm trailer brake controller operation using its instructions. Fluid loss, warning lights, or changes in braking deserve diagnosis rather than simply topping off fluids and continuing.
Check accessible slide-out seals for dirt, cracks, tears, gaps, or displaced sections. Look inside for dampness or staining near the room opening.
Clear debris from the slide’s travel path and observe its operation. Stop if it binds, scrapes, or moves unevenly. Clean and maintain the mechanism according to its specific instructions; do not assume every system needs lubrication.
For the awning, inspect:
Retract the awning before leaving the campsite, going to bed, or approaching severe weather. Have damaged hardware or fabric assessed before continued use.
Check around roof vents, skylights, antennas, and other roof-mounted equipment for visible damage or deteriorated sealant. Include exterior wall joints, windows, doors, and compartment openings in your inspection.
Look for gaps, separation, cracks, or evidence of water intrusion.
Access the roof only if your RV’s instructions permit it and conditions allow safe access. Do not assume every roof or ladder is designed to support an inspection. Arrange a professional inspection if you cannot safely reach the area.
Use sealants compatible with the specific roof or exterior material. Adding an unsuitable product over damaged sealant can complicate the repair.
Operate your refrigerator, air conditioner, microwave, cooktop, and other installed appliances according to their manuals.
Check for changes in cooling, airflow, ignition, unusual noise, or displayed fault codes.
Inspect serviceable AC return-air filters. Clean reusable filters or replace disposable ones as directed, and keep return openings and supply vents unobstructed.
Before testing propane appliances, confirm that their startup requirements are met. A tank-style water heater must be full before heating. If you smell propane or suspect a leak, stop testing and follow your RV’s emergency instructions.
Use a flashlight to inspect accessible areas beneath sinks, around the toilet, near the water pump, and inside plumbing compartments.
Check for:
Investigate recurring pump cycling rather than assuming it is normal. If you find a leak, shut off the water supply and pump before arranging repairs.
With shore power disconnected and other sources isolated as required, visually inspect accessible cords and connections for damaged insulation, corrosion, scorching, or loose fittings. Do not open electrical enclosures for this routine check.
Check battery charge and condition using the battery manufacturer’s guidance. Inspect accessible terminals without bridging them with tools.
Test interior, exterior, running, brake, and turn-signal lights.
Also test smoke, carbon monoxide, and propane alarms according to their instructions. Check replacement dates, battery requirements, and the fire extinguisher’s condition.
Refresh first aid supplies, flashlight batteries, and other emergency essentials. Inspect potable-water hoses, electrical cords, wheel chocks, and leveling blocks. Replace damaged items rather than repacking them.
Clean storage compartments and secure gear for travel. Note repairs, service appointments, and maintenance deadlines before they get lost in the next trip’s preparation.
As fall approaches, review reservations and organize cooler-weather supplies. Keep winterization planning separate from tasks needed to make the RV ready for immediate travel.
