We have purchase used 1996 Pace Arrow and new 2008 Sea Breeze and you still have issues. The last one we bought is pre-owned 2006 Sportcoach Encore on a Freightliner, with Cat motor and Allison Transmission. It has good bones. The automotive is rock solid, But you have to do your maintenance. I'm retired so I have the time and enjoy doing the maintenance.
The only thing we have had that was big issue was a $1.50 rivet broke on the slide rail. $1800.00 bucks later, oh well it happens. Plus you have to figure in updates....We have updated the TV's. The next big deal will be tires. They will be changed this season. We love taking trips in our motorhome so we keep it in tiptop shape.
The big thing is to have fun.
Happy Camping
Bye Dennis
