The weather is getting warmer. Are you going to your dream travel place, such as Historic Route 66, Texas Hill Country, Great Basin, NV, or a more beautiful place you scheduled? Whether you are planning on a short weekend trip or a long-distance travel across state lines. It is not enough to pack your bags; taking the time for a thorough inspection of your RV on the road will ensure a safer and more enjoyable trip.
To ensure a more systematic inspection and no details is overlooked, we have categorized the RV inspection items into three main groups as below. We have also attached an inspection file at the end of the article
- Powertrain system
-Exterior system
- Interior Systems & Living Amenities
1. Powertrain
It is the first step to inspect the engine and powertrain ( if you have a Towable RV (like 5th wheel, trailer, pop up camper, check the Pickup truck or SUV which is used for towing is necessary)
Check all fluid levels or leaks( like engine oil, coolant, and transmission fluid ). The fluid levels should be between the minimum and maximum values required by the manufacturer.
Their color and viscosity should appear clean and clear （ if it turn to black or dirty, please change it), and hoses should be free of cracks or bulges.
Check the engine belts for cracks, fraying, or a glossy, glazed, and ensure that their tension is appropriate. A worn or broken belt can lead you to a standstill on the road; therefore, changing the belt that is showing signs of aging or insufficient tension, meanwhile carrying a spare belt with you is a simple but highly valuable precautionary measure.
Check the braking and suspension systems.
The thickness of the brake pads, the condition of the brake rotors and the cleanliness of the brake fluid all require careful inspection.
When you press the brake, but it feels spongy or if you hear any unusual noises, please have maintenance come timely.
Check the suspension system and tie. Inspected for leaks, wear, or looseness.
Use a tire pressure gauge to measure the pressure of your "cold" tires (before driving), and inspect the tires for any cracks or bulges. Your spare tire, too, must be in optimal condition.
2.Exterior Systems
The exterior of your RV is not only a crucial aspect of the RV， the rv roof, lights, RV doors, cabins, slide topper system, awnings etc., directly affects your travel and camping life.
Wash your RV’s exterior thoroughly to inspect for any leak detection.
Check the body and chassis for cracks, leaks, or damage to ensure safe operation.
Check All exterior lights — including headlights, brake lights, turn signals, and marker lamps — must be functioning properly
RV Roof
If your RV roof is walkable, it should be on your checklist. The roof sealant coating will be damaged by UV and water over time. Regular inspection, care, and preventative maintenance will extend the roof's lifetime and save you a lot of money on replacing and repairing, even over USD800
Check the slide topper, especially without any awning or cover. The rain, dust, and UV will damage the slide box rubber seal; it will crack, lose elasticity, or become loose over time. Operate the slide box, and all details, if needed, we suggest add extra awning to keep your slide topper from damage.
RV awning if there is. The awning is one of the most easily overlooked exterior components, but sometimes the drop-off or damaged awning will ruin your travel.
Open and close your awning to check the sail track, brackets, and fabric are fixed well, no damage or break on the awning frame.
If any parts are loose or the fabric is worn, reinforce or replace them in advance.
no mildew, fading, or leaking of awning fabric.
Spending a few minutes on this maintenance is far better than facing costly repairs during the trip and ensures maximum safety.
If you need any replacement or repair, Awnlux as one of the top RV awning manufacture will be your good choice for choosing.
3. Interior Systems & Living Amenities
Interior inspections focus on three parts: Interior Furniture & Appliances, the electrical system, and the water system.
Interior Furniture & Appliances, such as Cabinets, drawers, and appliances, should be securely fastened to avoid shifting or damage on the road. and checking all furniture and appliances wiring carefully to ensure it had not been damaged by pests such as insects or termites.
For the electrical system, ensure the house and starter battery are full of charge, the terminals are clean and no corrosion.
To keep there is reliable power during travel, double test the inverter, charger, and lighting all in good condition.
Inspect the water system, test the pump for good operation, and in the kitchen, ensure the water heater and filters are working well, test the stove and water heater ignition. No leaks on the hose, tank, and propane system. Checking all fittings or connections with a soap-water solution
Propane alarms should be operational. smoke detectors, carbon monoxide alarms, fire extinguishers, a first-aid kits etc., what safety equipment you need should be prepared, and put in the place where they can be found easily to handle the emergencies on the travel.
