After much searching (ok probably not THAT much). I have yet to find a recommended cab to box spacing for an air ride cab. Since my truck has an 18 inch gap behind the cab where the exhaust sits. I need to run the exhaust down low and slide the box forward on the frame. I just don't want to go too close and cut the rear frame off too short
Is there anyone successfully running the air ride cab with a fixed box?
How much of a gap do you need?
I'm already going to have to run an accordion seal, since the back of a Volvo cab tapers forward near the top.
