I thought it might be helpful for other RV owners to write up a list of RV maintenance tasks, grouped by frequency. Of course, these are for our 2017 Tiffin Allegro Bus 40SP motorhome; other RVs may have different requirements, and may not have some features like water softener, dishwasher, etc. But most items would apply to any RV. If I missed anything, or you have any corrections or other comments, please let me know!
- Weekly:
- Test water hardness; regenerate the water softener with salt if needed (and if you have one).
- Monthly:
- Run the generator under load (e.g. with ACs running) for an hour; good for a travel day.
- Empty air tank drain valves.
- Clean dishwasher rim and filter.
- Spray electrical cord contacts with DeoxIT.
- Wash coach exterior with Wash Wax All or similar.
- 3-Monthly:
- Backflush water softener.
- Replace house and fridge water filters; I have 3-stage filters plus the built-in one and fridge filter.
- Lubricate window slides with Plexus.
- Lubricate entry door hinges with silicone lube.
- Invert fire extinguisher and shake to loosen dry chemicals.
- Remove shower drain cover and in sink to remove hair.
- Check Aqua-Hot antifreeze level; should be at HOT level just after shutting off; top up if needed.
- 6-Monthly:
- Replace ceiling AC filters (two different types).
- Sanitize fresh water tank.
- Vacuum dust under fridge; a couple of screws and clips to remove panel under front of fridge.
- Clean dryer vent from outside.
- Polish wheel rims with Purple Polish.
- Apply 303 Protectant to tires.
- Yearly:
- Replace dash AC filter. Accessed via generator compartment on rear wall.
- Make sure emergency exit in bedroom opens easily.
- Get waste tanks professionally cleaned.
- Get roof seams and joints inspected at service center.
- Get engine, generator, chassis lube, slide-outs, and Aqua-Hot serviced.
I hope this is helpful, Let me know of any updates!
