Thanks guys. Good stuff.
I have no idea what this thing will weigh, but it'll be heavy. I'm going to add HDPE runners on the back side, so i can tilt it over and slide it into the bed of my truck. In theory atleast.
I was going to make my heat diverter slide into the lowest rack runner. That way i can clean it, and modify if needed.
A second ash pan is a good idea. Maybe i'll size the ash chamber for a foil pan.
