It's a bit ott but I always intended on rolling a few campers with it but have used it on smaller cars, it's basically been adapted down the years as and when required.
Started life as some 2"x2" box tubing,
What started as two half rollers (for car hubs) evolved into this to be bolted to a camper chassis.
There's been one or two on it now
worth it's weight..
Oh and most people ask, the box tubing was bent with a run of the mill hydraulic bender and a little ingenuity.
Given the choice again though I'd buy a VIP roller from cjautos and sell it on once finished with
