Rotisserie or Rolling Cart - Pros and Cons

I built a chassis jig and then bought a rotisserie for less than I could buy the steel to build my own from a member. I absolutely NEED the jig until the body is structurally able to withstand the rotisserie. If you don't have concerns about the body twisting, folding (mine is a rusty vert), the rotisserie will serve you much better.

As already mentioned, you can always sell it when you're done.
