Now do it with a cross box in the bed.
I have hauled 144's with the box in, but the skis will slide up under the box a little bit. Originally I had a sheet of plywood down to help reinforce the tailgate area, small 2x2 block to keep the paddles from laying over and it would haul ok. Strap it in good. With a 144, it measured 44" from the back of the tailgate to the back of the sled bumper.
