My first Class A motorhome was a 1999 Bounder 34V I purchased new. A very nice unit. Mine did not have the tag axle. It had a Ford Chassis. We took this unit around quite a few Western states and also throughout the midwest and Southeastern states. No material problems in the years we owned it and lots of family travel memories tucked away.
The only real issue I had was constant rodent intrusion. I kept plugging up all the open spaces underneath that let them enter the unit. I found most of them by turning on all of the basement storage lights, then going underneath at night and plugging all the places that light was shining through. Apparently Fleetwood did not believe in using grommets or sealant around places where wire cables or gas lines, etc entered the unit. After getting all of them sealed up I was still getting the occasional mouse inside and finally found where the rubber seal around the firewall was soft enough they were literally pushing their way right through it. I fixed that and never had another one inside.
Usually you can tell the Ford Chassis vs the Chevy Chassis of that day at a glance because the Chevy Chassis had a narrower width...the front tires are substantially inside of the fender wells. It wasn't until the Chevy chassis was redesigned by Workhorse that the stance was widened.
