Thanks for the correction on the FL chassis.

10k is what the CFO tells me I spend a year.
Over the last ten years of ownership I have replaced, upgraded, or remodeled almost everything on the coach. I rarely have had to replace or repair something twice. The one exception to that has been the radiator. The point being that most of what I list is a one time thing.

We have a 99 model, 275K miles, owned for 10 years, and travel six months per year. We have spent almost as much maintaining and upgrading the coach as the original purchase price. And my labor is not counted in the $$$$. The 10K also includes tools I have purchased to do the work, such as industrial sewing machine and 1 inch impact gun as examples.


Tires
Batteries (there are 6 8D house batteries, although most go with Lithium now)
Radiator
Slide seals
Brakes
Reupholstered all the furniture, dinette twice
MCD blinds
Lithium batteries
Upgraded inverter
Rebuilt all air conditioners
Changed out Webasto burner control for Beckett
Moderate exterior painting to alter trim color
New Sunbrella all around
Installed air driver seat for CFO
Exhaust system replacement
Valve job and rings in generator motor at 7000 hrs
Tag axle bearings
Shocks
Tie rod ends
Headlight upgrade
Replaced carpet with LVT
A few windshields.

These are some of the things that come to mind.
