Routine RV Maintenance: What to Check Before a Trip

Summer is a popular time for road trips, but the hot Texas weather can affect your RV’s performance. Carrying out routine RV maintenance checks to keep your RV in working order might seem like a chore, but it could save you time and money later. Here are some simple checks to help you get started.

What to Check Before an RV Road Trip


Check your headlights, brake lights, running lights and turn signals. You should also inspect your lenses and clean or replace themĀ if required.

Coolant Level

Locate your engine coolant reservoir and check the coolant level is between the maximum and minimum marks. Most modern RVs have a sealed cooling system, so they shouldn’t need refilling between services. If the coolant level has dropped, consult a mechanic.

Tire Pressures

Check your tire pressures to ensure they comply with the manufacturer’s guidelines. You can find these either in your RV handbook or on the inside of the driver’s door. If your tire pressures are low, it could indicate a slow puncture.


Inspect your windshield for chips and cracks and if you notice any damage, get it repaired or replaced immediately. You should also check that your wiper blades are secure and in good condition. If your wiper blades make a noise, judder or leave unwashed margins, replace them with new ones to avoid the possibility of damaging your windshield.

Following checking the exterior of your windshield, top up your windshield washer reservoir with a good quality windshield washer fluid to help keep your windshield clean while you’re on the road.

Oil Level

Check your RV’s oil levels are between the maximum and minimum marks on your dipstick. If the oil level is low, top it up to the maximum mark. When filling the oil reservoir, add oil slowly to avoid overfilling.

Air Conditioning

Inspect your air conditioning filters and clean or replace them, if required. You should also check the condition of your cooling fins and clean them. If you have bent fins, use a dull knife to straighten them out.

Lug Nuts

Check the torque of your lug nuts with a torque wrench. If your lug nuts are loose, tighten them to the level of torque specified in your RV handbook.


Inspect your batteries for signs of corrosion, dirt, and abnormal wear. Any fluid on or around your battery could indicate that your battery is leaking electrolyte and needs replacing. You should also check the battery fluid level. If the water level is low, top it up with distilled water.

Water Tank

Drain and clean your water tank before refilling for use. Be sure to add a water tank sanitizer to eliminate any bacteria and algae that may be present in your system. When using sanitizer, remember to flush any residual sanitizer out of your tank prior to filling it with water.

Electrical System

Check that visible electrical cords, plugs and sockets are in good condition and replace them, if necessary. You should also inspect your circuit breakers and fuse boxes for signs of deterioration. If you have any doubts about the safety of your electrical system, get it tested by an electrician.
