RV maintenance

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:
  • 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.

I hope this is helpful, Let me know of any updates!
