Been a long time gang.

I have a homemade grill/off set charcoal grill.
I want to set it up for a rotisserie. It's 27" wide, 24" deep and about 16" tall.

Any recommendations on brands and placement?
I was thinking if I put it in the center of the grill that it would be too close to the coals I lay across the back. Maybe I off set it 4" closer to the front of the grill from center, leaving space between the back row of coals and the meat.

Thanks for any and all help.
