My first RV was a Class B Roadtrek on a Dodge chassis. Since I'm single, I figured that it would serve my purposes and it does just that for some folks. But in my case, it didn't take long to hate a kitchen that doubled as a shower, a closet that did double duty as a "water closet" (toilet), and a dinette that doubled as a bed, unless you're over about 5'6". The clincher was a Dodge factory recall on the drive shaft universal joint. On my Roadtrek, the grey water tank was beneath the drive shaft and had to be removed to do the repairs. Dodge wouldn't pay to have the tank removed since it was an aftermarket add on. Roadtrek wouldn't pay because there was nothing wrong with the aftermarket add on.
So I paid.
Followed immediately by trading it in on a Fleetwood 'C'. NOW I'm a happy camper.
