Semi and Trailer Repair

RVs, or recreational vehicles, allow you to travel and live comfortably on the road. With an RV, you can explore the open road while enjoying amenities like a bed, kitchen, bathroom, and living space. However, RVs require regular maintenance and care to keep them in top condition. Knowing what maintenance to perform and when will help your RV last for years of adventure.

Annual Maintenance

Several maintenance tasks should be performed on an RV annually. Doing these routine jobs yearly will help prevent breakdowns and expensive repairs down the road.

Change the Oil

Like any motor vehicle, RVs need regular oil changes. Most manufacturers recommend changing the oil every year or after about 5,000 miles of driving, whichever comes first. Use the type of oil specified in your owner’s manual and make sure to also replace the oil filter. Changing the oil annually will extend the life of your RV’s engine.

Inspect and Replace Filters

RVs have several filters that require replacement each year. Check and swap out the air filter, fuel filter, and engine air filter annually. Replacing these filters prevents debris from building up and allows your RV systems to run cleanly. The generators on larger RVs also have oil, fuel, and air filters that need yearly inspection and replacement when necessary.

Check Belts and Hoses

Inspect all belts and hoses including serpentine belts, radiator hoses, vacuum lines, and transmission cooling lines. Look for cracks, wear, and leaks. Replace any belts or hoses that are deteriorated. This prevents breakages that could damage your engine or leave you stranded.

Lubricate Moving Parts

Lubricate any moving, mechanical parts on slides, jacks, wipers, steps, and appliances. This allows them to move smoothly and prevents annoying squeaks. Consult your owner’s manual for lubrication points and recommended products.

Seal the Roof

RV roofs take a beating from the elements and need to be re-sealed annually. Use a high-quality sealant made for RVs to prevent leaks. Carefully clean and prepare the roof before applying sealant. Avoid seam tape, which can trap moisture and cause early deterioration.

Deep Clean the Interior

Do a deep clean of the RV’s interior each year. Shampoo carpets, sanitize surfaces, wash curtains, and clean ceiling vents. This removes allergens, prevents mold/mildew growth, and keeps your RV’s interior looking its best.

Check Propane System and CO Detector

Have a qualified technician inspect the propane system and carbon monoxide detector annually. They can check for leaks and make sure appliances are operating safely. This helps prevent dangerous propane leaks or CO poisoning.

Lubricate Locks, Hinges, and Latches

Apply lubricant to all locks, hinges, latches, and any moving hardware on cabinets, doors, and exterior storage compartments. This prevents corrosion and keeps them operating smoothly.

Seal and Inspect Windows

RV windows take abuse from rain, wind, and the vibrations of travel. Annually clean, re-seal, and inspect window seals for leaks or cracks. Catching small leaks early prevents major water damage. Also, lubricate window slides and moving parts.

Have Appliances Serviced

The appliances in your RV should be inspected and serviced once a year. A technician can clean, lubricate, calibrate, and safety check appliances like the refrigerator, range, furnace, water heater, and generator. This tune-up maximizes appliance life and safety.

Check Tires and Tread Depth

Inspect all tires, including spares, for wear, cracking, bulges, and adequate tread depth. Replace any tires that have insufficient tread left. Rotating the tires helps them wear evenly. Tires degraded from UV exposure and the weather should also be replaced as needed.

Test Electrical Systems and Batteries

Have an electrician test your RV’s electrical system and batteries. They can spot loose connections, damaged wiring, and failing circuit boards. Testing the batteries shows if they need replacement. Addressing electrical issues promptly is crucial.

Inspection and Resealing of Roof Seams

One of the most important annual maintenance tasks for RVs is the inspection and resealing of the roof seams and joints. The roof is constantly exposed to the elements, undergoing expansion and contraction that can cause cracks. Have a professional inspect all roof seams and seals, looking for any gaps or leaks. Reseal the roof with a high-quality sealant made for RVs. This prevents costly water damage from leaks.

Spring and Fall Maintenance

In addition to annual maintenance, some jobs should be done in the spring and fall. Make a regular habit of tackling these tasks twice a year.

Flush the Plumbing System

Flushing the RV’s plumbing system should be done in spring and fall. This clears out any sediment, hard water deposits, and stagnant water from the tanks, pipes, and water heater. Flushing prevents plumbing blockages and foul odors. Use RV plumbing antifreeze during winter flushes.

Clean and Disinfect the Fresh Water Tank

Sanitizing the fresh water tank in spring and fall keeps it clean and free of contamination. The tank should be emptied, scrubbed, allowed to dry, and then sprayed with a bleach solution. Rinse thoroughly before refilling. This prevents harmful bacteria or mold from growing.

Inspect Slide Rooms

Slide-out rooms or slide-outs are a common feature on RVs. The rooms extend horizontally to create more living space. Check slide-out rooms carefully in the spring and fall for any damage, wear, or debris buildup. Lubricate slide components and seals. Catching problems early prevents costly slide-room repairs.

Detail the Exterior

The RV’s exterior should be detailed twice a year to maintain its appearance. Give the outside a thorough cleaning and apply wax to protect the finish. Use cleaners made specifically for RVs. Waxing helps repel rain, snow, and dirt. Check for scratches, chips, or damage that could lead to rust or water intrusion.

Winterize the Plumbing and Appliances

RVs used in cold climates need winterization to prevent system damage when freezing occurs. Have a technician winterize the plumbing and appliances in the fall by draining pipes, adding RV antifreeze, and preparing components for storage. Your owner’s manual outlines winterization steps. Thawing, flushing, and restarting systems in spring are also needed.

Service the Generator

If your RV has a built-in generator, it should be professionally serviced before winter layup. A technician will change fluids, check and replace filters, inspect hoses/belts, clean components, and make any needed repairs. Proper winterization allows the generator to start up promptly in spring.

Check the Chassis

Examine the RV’s chassis in fall and spring. Look for rust, damaged coating, loose parts, and frame cracks. Repair any issues promptly to prevent safety hazards. Lubricate moving chassis parts like hitches, jacks, and suspension components to prevent wear and noise.

Monthly Maintenance

You should also do maintenance on your RV monthly when it is in frequent use. Making these simple checks part of your routine will extend your RV’s lifespan and prevent headaches on the road.

Check Tire Pressure and Tread Wear

Once a month, check the tires for proper inflation pressure and even tread wear. Under-inflated tires can cause blowouts and uneven wear. Keeping tires inflated to the recommended PSI extends tread life and saves you money on premature replacements.

Inspect and Clean the Exterior

Give the RV exterior a quick cleaning, inspection, and sealant touch-up monthly. Remove debris, wash surfaces, and touch up any sealant cracks that could lead to water intrusion. Check that all exterior components including lights, doors, hatches, vents, and latches function properly and are free of damage.

Test Detectors and Alarms

Make sure all safety detectors in your RV are working monthly. Push test buttons on smoke, propane, and CO detectors. Check that alarms sound loud and clear. Replace any detectors that fail the test. Functioning alarms are critical for safety.

Check Engine Fluids

Check all engine fluid levels monthly when the engine is cool. Top up the oil, transmission fluid, coolant, power steering fluid, and any other reservoirs as needed. Low fluid levels can damage RV components. Review your owner’s manual to locate fill points under the hood.

Inspect Slide Out Seals

Slide out seals and take abuse during operation. Inspect them monthly for any cracking, hardening, or gaping that could allow water intrusion or debris buildup. Have worn seals replaced promptly. Lubricate slide components with proper slide lubricant.

Check Auxiliary Battery

Turn on lights and appliances to test the auxiliary battery monthly.Start the generator if needed to maintain appliance use for 30 minutes to an hour. If lights dim or appliances lose power quickly, the auxiliary battery may be failing and need replacement.

Clean Exterior Storage Compartments

Open and wipe down exterior storage compartments monthly to prevent dampness and mildew. Make sure compartments are free of leaks and debris. Store gear neatly to maximize space. Having organized exterior compartments makes travel preparations easier.

Inspect and Seal the Interior

Go through the interior monthly checking windows, vents, seals, and surfaces for moisture intrusion. Re-caulk or reseal any areas as needed to prevent water damage. Look for leaks near skylights, hatches, slide-outs, and AC gaskets which are common problem spots.

Test Appliances and Accessories

Turn on and test all appliances, electronics, lighting fixtures, and accessories monthly. Verify that the fridge, microwave, entertainment center, lighting, power outlets, etc. are functioning. This allows you to spot problems early instead of when gear fails during a trip.

Check the Propane System and Supply

Examine the propane system and monitor tank levels monthly. Look for any loose fittings or connections requiring tightening. Make sure propane covers are secure. Refill tanks that drop below 30 percent full. Identifying propane issues now avoids needing emergency fills mid-trip.

Ongoing Maintenance

In addition to monthly, seasonal, and annual maintenance, there are ongoing maintenance habits you should build into your RV lifestyle.

Keep the interior clean

Regularly cleaning the interior keeps your RV fresh and prevents mold or mildew. Vacuum carpets, mop floors, dust surfaces, and clean the bathroom as needed. Immediately clean up spills, splatters, or leaks. Remove shoes to avoid tracking in dirt. Doing light cleaning often makes deep cleaning easier.

Maintain water and holding tanks

Adding RV enzymatic tank treatments monthly keeps plumbing lines and tanks functioning well between thorough flushes. These break down waste, control odors, and prevent buildup. Always keep black and grey tanks emptied, rinsed, and flushed. Check tank levels before travel and dump frequently.

Keep sealant and coatings touched up

Inspect sealant around windows, doors, roof fixtures, and slide-outs regularly. At the first sign of gaps or shrinkage, clean and reseal areas to prevent leaks. Use RV caulk and recoat surfaces like the roof annually. Touch-ups take little time but prevent costly water damage.

Remove snow and debris

Never allow snow, ice, leaves, or debris to accumulate on your RV roof. The extra weight stresses the structure and can allow water infiltration. Use a soft brush to clear the roof after snowfalls or storms. Inspect attachments like antennas and vents for tightness and moisture seals.

Maintain the generator

If equipped with a generator, follow the manufacturer’s maintenance schedule for proper care. This includes regular exercise to prevent fuel varnishing, oil and filter changes, tune-ups, and winterization. Never exceed your RV’s electrical load when relying on generator power.

Proper maintenance is crucial for the longevity and reliability of your RV. Following the manufacturer’s recommendations creates good maintenance habits. Perform annual, seasonal, monthly, and ongoing tasks promptly. Schedule maintenance with qualified RV technicians for major jobs. Investing a little time regularly into your RV’s care yields big dividends by preventing expensive repairs and downtime. With proper maintenance, your RV will provide many miles of memories as your home on the road.
