I am only 54, but start camping as a child with my family. Once on my own I started with a tent, then popup, travel trailer, fifth wheel and now a used Class A DP.
Someone else said something similar to this... with a TT or 5ver, the adventure starts when you get to you destination and get setup, with a Class A, the adventure starts when you crack the engine.
We enjoy our Class A and don't think I could ever go back. We were able to purchase a Class A DP for actually a lot less than what we spent for our 5ver and truck.
