This looks in some ways to be the perfect viable standy (but too tiny to have a bathroom). The trailer is made by Whetzel Trace Trailers, and they also make teardrops.
Now in production, the The Whetzeldorf is a modern version of a compact camper made in 1957, by Martin Metzendorf in West Farmington Ohio. Metzendorfs were made from 1957 to about 1966, and all models known to exist were built with a 10 ft long body. We came across one that is only 8 ft long, but has all the amenities of its larger cousin. No known information is available and probably was a prototype or worlds Fair exhibit. It has become very popular at the vintage shows we have taken it to, and so we decided to build a similar model.
Dimensions:
76" wide
98" long
76" high
Weight: 1200 #
These trailers look to have a dropped floor.
According to the Small Trailer Enthusiast web site, the trailers run ~ $7500.
