For use it is simply the trailer. Our old pop-up was simple the pop-up. My Aunt & Uncle who just got a new AirStream insist on it being called a Travel Trailer. Heaven forbid that you might call it a Camper since they don't Camp, they Travel. Different strokes...
We have a old M-26, same as a 3023. We frequent full hook-up sites but I prefer primitive. Difference between the DW and I.
