Buying a Former Rental Class C. How many of us out there?

Wow! 85 Pages.
What is the current opinion of rental sellers? Is one better than the rest?

CA sends me a list every month and the prices are always better than what I find other places. The high miles do concern me, but CA provides a 12 month/12,000 miles powertrain warranty. Any good?

I'm focused on the 23U since it's just me and a pooch after my wife died. I like to go out for 2 to 3 weeks at a time but wondering if others have had one and wished they had bought bigger.

Thanks!
