Welcome! I am a current ex-rental owner that has had my Class C for over 10 fun-filled years with few issues. We use RoadAbode 9 out of 12 months each year.
1 - Mine had way less miles when we purchased.
2 - $25K seems high for a 19 foot unit, but we don;t know what that is buying you in options or amenities.
3 - Cruise America and El Monte both have good ex-rental sales programs - maint is done and records should be available to you. That can't be said for all private sales. That said I bought from a smaller dealer that had a small rental fleet. Still kept good maint records.
I agree that there are plenty of used motorhomes out there. There are deals to be had. Don't rush. Research. Read the link that IAMICHABOD recommended. Ex-Rentals CAN be a good value.
Good luck with your search. RVing is a great lifestyle to be a part of.
Check the blog link for some updates and places we've been.
