Casita vs "conventional" small trailers

I'd love one of those, but not sure I can go back after having a trailer with slideouts! I sure do miss our little Nash 22RB though. We could take that thing anywhere, we could fit into any spot (include a tent spot if push came to shove). Current trailer is 32' long, we've had to shoehorn into spots before.

The biggest advantage is obviously the fiberglass exterior and no rubber roof to deal with. Insulation doesn't really matter, because its so small its super easy to keep warm or cool.
