Today I came across this tiny trailer:


This is the Vagabund Campingwagen from Germany - probably from the late 50s or early 60s, judging by the DKW 200cc motorcycle that's the tow vehicle.
The Vagabund page from Oldiecaravan.de is in German but if you paste the link into Babelfish you find out:
Unladen weight 58kg / 128lb
Body length 2.20m / 7' 2"
Body width 1.20m / 4'
Body height 1.38m / 4' 6"
The chassis has torsion bar suspension (that "ensures calm driving"!)and the body can be unbolted to use the chassis as a utility trailer. The body is made of 4mm plywood "strengthened by light alloy angles".
Makes Steve Wolverton's Cowper at 400+lb seem a bit heavy, don't it?
