Our RV progression went like this:
~Tent, rarely used
~Travel trailer, rarely used, traded in on single-wide trailer house for lake property
~Years pass with no camping
~Thirty-foot Class A motorhome, used quite a bit the first couple years
~Small simple pop-up, bought six months after Class A
~Three years later, new fully optioned, giant economy-sized pop-up
~Now need to sell Class A
Needs change over time. There's nothing strange about going from a Class A to a pop-up. It's not a matter of stepping down, it's a matter of getting the right tool for the job to adapt to changing conditions. What worked for us ten or twelve years ago does not work now. We got pop-ups because we started doing serious traveling, thousands of miles at a time. When we bought the Class A, we were mostly doing weekend trips close to home. Oh, and gas cost $1.80/gallon then. Now that we're doing long trips, the pop-up strikes a good balance between convenience, comfort, and fuel economy.
Our next step will most likely be an A frame pop-up of some kind. Or using our mini-van as an RV on a temporary basis. Or both.
It will be a change but you will enjoy the best of camping! You will feel outdoors similar to a tent but will be dry and have a comfortable bed. (We got a spring mattress in our pop up)
