Nice set up. Did you use the hinge pockets as your mounting points?
Thanks
I did mount using the hinge pocket bolts on the A-pillar and the strike attachment at the B-pillar. A standard rotisserie uses the body mount bolts, but the fronts on my cab were gone, and I needed access to the floor to patch it. The only downside is access to inside of the cab. I can squeeze in there, but it's getting harder as I get older.

To the OP, If your plan is to eventually do a full size car, and not just a pickup cab, I'd probably go with the standard rotisserie setup you're looking at.
