Just curious- what are you looking for that you can't find used?
I grew up camping in a pop-up and was looking for a small (8' box) tent trailer when I stumbled onto our Scamp
. Definitely less space with four people, but so much more solid and comfortable in bad weather, and never any wet canvas to fold up. You will enjoy the upgrade. One thing you will have to deal with is converting between beds and seating in bad weather. Not a big deal, but it does take a few minutes. In good weather, of course, we leave the beds set up and live outside: cooking, eating, lounging, exploring, etc.
The taller profile does make for somewhat harder towing compared to a tent trailer of the same weight
, especially when you add high altitudes, steep grades, and winds to the equation.
