I have a 2018 Duramax SWB Crew Cab - 3/4 ton. I have a RCI standard tool box that goes across the back right behind the cab. I think it's ~ 18" long. Question is: I've been thinking of stepping up to a 5th wheel, and probably a pretty large one. Can I keep the tool box in place? I've seen some of the hitches that seem to off-set the trailer rearward that probably wouldn't conflict the box. Just wondering if there is anybody with a tool box in pulling a 5th wheel.
Thanks,
