Check out the link below. It has low weights (2540 UVW and 210 hitch) as well as a good layout with dry bath, queen bed, large fridge, overkill a/c/heat and jack-knife sofa. Downside is aerodynamic profile although it has some forward slope it'll probably have about 20 less miles of range than a similar weighted pop-up.
Retro Travel Trailer – 135 | Riverside RV
I love that retro look.
I considered this trailer a while back and rejected because it seemed like it would have way too much drag.
Sure has a lot of nice features, though. I might have to give it another look!
