I have 3 cabs in progress now and all are on rollers.
I made a f100 small trailer and a cab or engine or bed will set on it and I pull it with my tractor.
I also use a dolly on wheels comparable to above posts-but able to roll in gravel and sand--and goes in my sandblasting booth.
I also have another small trailer for cabs -etc and as long as it rolls smoothly--a cab will set on it for prep or paint.

I built this so it could be used later when I start work on my pickup. The pipes you see going length wise just bolt into the end pieces. I built this before I built my rottiserie.
