Also, if the 5th wheel rails are installed correctly they bolt through the bed and to brackets that bolt to the frame. There should be no real pressure on the bed itself. The GN hitch should bolt to the frame and run from side to side underneath the bed with the ball sticking up through a hole in the bed. I personally feel like the GN is stronger but it seems like the 5th wheels are rated higher. I converted my camper to GN but I do like knowing I can drop the 5th wheel hitch into my rails if I need to pull one.
