I'm sure others will have different opinions which is probably why no one answered your question so I'll take a stab at it.
When you change your engine oil grease your coach at the same time, elevated of course. Rear axle, check oil, if OK, leave it. The rear end oil doesn't have to go thru combustion etc like the engine oil.
Antifreeze, check and maybe change every 2 - 3 years, it depends. Transmission fluid, if its red and fresh looking, and tranny works good, fine. Only checking it if it is full.
Maintenance is a very personal thing. Over-kill is better than Under-kill. When it really comes down to what these machines can do, it is surprising.
I believe in: Don't fix whats not broken, do not use dirty or contaminated fluids, check for proper fluid levels, keep things tight, use your discretion.
Hope this helps,
Sean
