I will warn that when looking at used units online, be sure to ask if the pictures are recent.
I drove 3 hours to look at a used camper that looked great in the pictures, only to discover that the pics were at least a couple years old. Most likely from when the current owner had bought the unit.
The camper I was looking at was in much worse shape than when the pictures were taken. With the cash in my pocket, I let the seller know I was not interested in a project camper and drove away.
A lot can happen in a few years if not taken care of.
