I'd guess that there's a minority of folks on here that got exactly what they wanted on their first try. Some live with it and some change.
My first RV was a class 'B'. I'm single and figured that was all I needed. The bed was also the dinette table. One of the closets was also the toilet. The kitchen was also the shower stall. And it was still too tall to fit in a parking garage and too long to park at a single parking meter. On top of that, it turned out that I'm a 'visitor', not a 'camper'. More than once, I came back to the CG and had to park in a different spot - if one existed. So I bought a 'C' and pull a Jeep toad. Nobody's fault. I didn't know how I was going to use it when I bought it.
So, I swapped for a 'C' and pull a Jeep toad. Full time bed, bathroom, shower and dinette. And when I pull into an RV park, I have the Jeep to go exploring.
The point - If you aren't enjoying what you have now, don't be afraid to change. At least you now know what you don't want.
