====================
I can find no date for this Champion Company Doo-All ‘Jeep” Trailer brochure. Give only CJ-2As are shown, I initially thought this was published around 1948. However, the lack of Jeep wagons or trucks may indicate the brochure was published earlier than that. The from number is S-3-T.
This first 8″x11.5″ page is the front page:
The brochure opens horizontally to review a second page.
The right page opens horizontally again, to reveal a trip-fold:
This is the back of the brochure:
This is the back of the brochure when fully opened:
I’d like to have one of doo-all trailers. Appears to be built well and really versatile. Much more useful than utility trailers today. Anybody ever see one in the wild?
JW,
If I had seen one, I probably wouldn’t have recognized it as being Willys related. I will watch more carefully.
Additionally, a company began in the 1990s producing Champion trailers, so doing searches for Champion trailers hasn’t been very useful.

Note, this is a trailer and not a semi-trailer, Bantam, Spen, Knox, most boat and house trailers are semi-trailers, the weight rests on the rear bumper or hitch of the vehicle. The Champion trailer has its own ‘fifth wheel ‘ so it can carry much more weight.
JW,
Gary sent me this link to a Champion trailer he saw for sale: https://hudsonvalley.craigslist.org/tro/d/saugerties-side-dump-mining-trailer/7542727821.html
It looks like the Champion Roll Dump model.
– Dave
Looks like it is currently setup to go on a tractor with a 3-point hitch. It does not seem to be severely modified, looks like front wheels would still bolt on, but I bet they would be hard to find, The ad does not state that the front wheels are available.
