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:

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!
