Here's a cute little (and I mean little) Curtis Retro trailer I saw at the Portland Expo Center RV show last week. The salesman said it was modeled after an old Shasta trailer. No wings, unfortunately.
15' long.
I love the chrome dome hubcaps.
Stepping in to the trailer there's about 1 ft of floor in front of the door that's higher, then the middle of the floor is a ditch that's been lowered 7-8 inches so that you don't hit your head while standing inside. If you were much taller than me you'd still hit it. Very cramped. This coming from an rpod owner. It has a lower profile than the pods' so maybe better mpg.
I didn't stay around long enough to look much, but I liked the retro design and colors. $14k at the RV show.
