Eight RV Annual Maintenance Tasks

It’s almost the end of November and I’ve been busy working on my Fall To-Do List.  This to-do list is mostly annual maintenance items – maintenance on my house, vehicles, the RV, and maintenance for me.  It’s the stuff that should get done each year to keep things (and me) in working order.

As opposed to doing these things throughout the year, I tend to plan all this work for the Fall when I’m not traveling.  I pack it all into a 6 week window, so it all gets done right before I head to Florida in December.

I don’t usually write how-to type posts, but since I’m “knee-deep” into it, I thought I’d share the RV specific annual maintenance items that are on my Fall To-Do list.  Many of these items are buried in the RV’s Operations Manual and are in addition to the monthly items (e.g., tire pressure, battery water levels, slide and step lube).  Some are just common sense.

For a veteran RVer, these items are probably not new to you.  But for someone new, they may be of interest.  It’s not a big list, just eight things that I make sure get done each year.

1. Wash and Wax the RV

This is pretty straight forward.  I usually wash the RV a few times throughout the year, but I give it one final wash in the Fall before I winterize it.  After the Fall wash, I use a spray on wax (Turtle Wax Ice Spay Wax) on the entire body.  The spray wax is easy to apply with a couple of micro fiber cloths.  One bottle of the wax is enough for two waxings of my RV.  I also wash the roof at this time.  The roof on my RV is fiberglass and it tends to get some mildew spots over the course of the year.  I use a soft brush with soap and warm water to clean the roof.

2. Sanitize the Water System

I sanitize my water system twice each year – once in the Fall and once again in the Spring before I start traveling.  It’s easy to do.  For my RV, I mix 1/4 cup of bleach into a gallon of water.  I pour two of these gallon / bleach mixtures into my water tank.  Then I fill the water tank and run the water through each faucet / fixture until I smell the bleach.  My fresh water tank holds 31 gals and this mixture provides a bleach concentration of 50 ppm.  I let the water sit for 4 hours, drain the whole system, and then refill with fresh water.  That’s all it takes to sanitize the water system.

3. Flush the Hot Water Tank

While I have the hose out and refilling my fresh water tank, I take some extra time and flush out the hot water tank.  My hot water tank doesn’t have an anode rod.  So it’s easy just to release the pressure valve and then remove the tank drain plug and run fresh water through it.  If you do this, make sure the water heater has been off and the water has cooled down.

4. Perform the Generator Maintenance

I use my generator frequently during the camping season and run it each month as recommended in the Operations Manual.  I usually put about 30 hours on the generator each year.  In the Fall, I change the oil, change the air filter, and clean out the spark arrestor.  This keeps my genny starting and running smooth throughout the year.  The key to keeping a generator running smooth is to run it often.

5. Test the Propane System for Leaks

Each year when we go to Florida, I schedule a service appointment with the RV dealer where I bought my RV (Lazydays in Tampa FL).  One of the things I have them do, is test the propane system for leaks and clean / check each propane appliance (clean the burn chambers, adjust igniter).  It’s a good thing to have done each year.  One year, they found a stuck shut off valve and another year they found a leaking regulator.

6. Change the RV Oil and Filter

I put about 20,000 miles per year on my RV.  The oil change interval on my 2014 Winnebago View is 15,000 but I do it every 10,000.  Usually in early Summer and again in the Fall.  I’m a shade tree mechanic and do the oil change myself. The Mercedes-Benz diesel engine in my RV takes 13 qts of oil and the oil has to meet a specific MB spec (229.51).  There’s only two oils that meet this spec – Mobil 1 and Valvoline MST Syn Power.  The filter requires a special tool to remove the filter cartridge.   You can buy the tool on Amazon for around $30.  Overall, it’s a pretty easy process.

7. Clean the Electrical Supply Plug

The plug on the end of the RV electric cord can get worn and should be inspected each year.  A bad or worn electrical outlet can cause damage to the plug (overheating and charring).  Each time I plug my RV into an electrical post, I check the plug to see if it’s getting warm.  I carry a non contact laser thermal sensor to check the plug and breaker temperature.  A worn outlet will heat up due to arcing caused by a poor connector.  The heat may become severe and melt the plug and char the connectors.  Each fall, I check the plug and clean the contacts with steel wool or emery cloth.

8.  Remove All the Food Items

I live in a climate where I need to winterize my RV for a few weeks before I leave for Florida.  As part of that process, I remove all food items so they won’t attract critters.  I also think it’s a good idea to do this even if you don’t have to winterize.  It’s good to get rid of those left over crackers that someone gave you at a happy hour a few years ago, toss the tuna cans that expired 2 years ago, and remove the peanut butter jar that’s been there since you bought the RV.  All food (well maybe not Twinkies) has a shelf life.  Each Fall, I remove everything, clean the draws and cabinets and restock with fresh stuff once I get to Florida.

That’s it.  The eight things I do every year to keep my RV in good working order.  Please leave a comment if you have any questions or would like to add items.

    Great list! I would add:
    applying dry lube to slideout tracks and cleaner/preservative to slideoutvgaskets and door seals.
    Inspecting/replacing wiper blades
    Washing tires with soap and water, drying and applying 303.

    What kind of hot water do you have, Gas or Electric, is it constant hot or only on demand. If it’s electric does it have one heating element or two? Great Article, where to in Florida? Thanks Mike

      I have a two way hot water heater that runs on either propane or electricity (110). It has a 6 gal tank so you need to have it on ahead of time to get hot water. I only run it when I need the hot water. We spend the winter in Fort Myers Beach each year, but also spend a fews days in St. Augusitine Beach, Tampa, and Sietsa Key Beach.

    A couple of add ons:
    Inspect undercarriage for any damage or loose wire runs. Check stabilizers, shocks and springs for any damage or unusual wear. Use zip ties to secure wires.
    Test all electrical outlets with a tester for proper operation.
    Replace batteries in smoke/propane/carbon monoxide detectors as needed.
    Check all exterior lighting for proper operation including headlights/turn indicators/clearance markers/brake lights and four way flasher.
    Clean flooring and apply appropriate sealer to enhance appearance and longevity.
    Test/clean/lube stabilizer system.

    Nice list. Thanks. A few questions… What’s an unacceptable temp on the plug? Has anyone found MB service anywhere else than Freightliner? How often and how many miles should i expect from the tires?
    Thanks again. I just purchased a View in May and your blog has been very helpful.

      On the plug temp, if it’s hot or very warm to touch then that’s unacceptable. I’ve run my AC unit nonstop in FL and the plug will get just a little warm (90-100). On one pedestal, I was getting a consistent reading of 120 degrees with nothing running and that was a problem. I had them change the outlet and it lowered the temp. I only get my MB service at MB. They seem to have the only diagnostic computers to read the MB codes. Tire wear depends on the care and alignment on the vehicle. I got 37K on my OEM Continental tires. I probably could have gone 5K more, but I was leaving on a long trip and didn’t want to deal with tires on my trip. I have 30K on Michelins and they still have plenty of life left.

      I first drain the hot water heater tank making sure it’s off and the water is cooled. I leave the drain plug off. I make sure all the faucets and fixtures are off. I then hook the hose to the city water connection like I would if I was hooked up at a camping site and turn the water source on. The water will try to fill the tank but run out the drain plug hole flushing the tank in the process. I run the water for a couple of mins then turn it off. Reinstall the drain plug and then turn the water back on to fill the water heater.

    All of your articles are very helpful to me as I also recently purchased a new Winnebago View. Thanks for keeping us informed and please continue these blogs.

    Thanks for the excellent posts you supply for us.

    Since I’m new to my 2025 View it is VERY helpful to me.
