Nice Dave..over the next couple weeks I will be cutting some tubes and lying them on the roof, to see where I would place them. Behind the front seats? Closer to the rear of the rig?
I think a 4-5" tube inside an insulted 6-8" is the way to go. The insulted tube would actually come all the way through showing as a fat stack. Bigger is better....LOL
Also will be drawing up some sketches.
Thanks for feedback and info...unique is always what I'm looking to do. Staying away from "that looks stupid"....
