the ONLY thing i could see this doing is getting your exhaust up and over your enormous fifth wheel.... but this guy prob dont even got a fifthwheel
Actually last year when I was towing my 5th wheel over to the coast, I saw a cummins at fuel stop that had stacks and a big 5th wheel. There was black soot all over the front of the 5th wheel and the guy was telling me how much he hated the noise and the soot on his trailer from the stacks. So you'd have to have some pretty tall stacks to get over the trails these days.
