I am following this. I have a 2021 Phoenix 367BH, tow vehicle is 2018 Ram 2500 Cummins. Fifth wheel sits nose high but I think the last time I measured I had 6 inches between trailer and truck bed. I think the only thing I would benefit by using a Goosebox is gaining bed space, not much help to lower the front of fifth wheel?
