...kinda related perspective: Our
Casita was hands-down the easiest towing of several travel trailers we've owned over the years -- "slick" & rounded fiberglass, reasonably aerodynamic and light. That said, and as indicated above, the practical & useable space tends to shrink a bit as us campers began to age a bit
. We loved and used the "Cassie" for a number of years, but sure do enjoy a much larger camper these days due to having a "big" walk-around bed, a real (non "wet") shower, a slide and lots of really useable space, equipment & storage. "Squarish", lower MPG and 6,000+ lbs. vs. the -3,000 and easy tow of the Casita is well worth it in our old(er) age.
