I would add rear axle grease(oil) to your list. and brake hoses, I ruined a new tire 200 ft from installation due to a locked up caliper just a couple months ago. Old hoses tend to brake on the inside and cause a check valve effect this causes the caliper to not return when you let off the peddle. Another thing I would do is take it to an RV dealer for a safety check of the coach systems. Mine found a fitting leaking on the LP regulator. I had them replace the whole regulator (28.00), and date code your tires, replace them if they'er much over 5 years old regardless of tread remaining. Peace of mind will make your life easier and safer for you and the ones you share the road with.
