I found these pics of a unit made by Zimmer of Detroit MI in @1949
it appears. It was called the Wee-Zim, a Sportsman's Trailer Home.
It is very similar to the Winter Warrior design, except it has solid walls
folding up to join the sections together and it has a drop floor in the
rear section, also with solid sides it appears.
I wonder how many were produced? -or- Was it a design
they were trying out? It appears to be included in a brochure for the
1949 Zimmer trailer coaches, so they must have made them at least
that year I'd speculate.
Here are the Pics it had:
I find it fascinating that a lot of these design ideas go way back, or
have also occurred elsewhere.
