Well, I have a, I guess? custom bed but pretty standard from the Mfg, as I have a SxS and needed a 10' be to carry it when needed.
I had to have the tie downs for the bed reinforced to the frame so as to attach the tie downs to the rings on the bed instead of the the frame per se.. still attached to frame, but I just hook up to rings in the bed.
Suggest back up lights on the back of bed and head board just in case.
Might have them put on some side covers to secure gear on the sides.
There are probably a few more things but probably wouldn't apply like I have winch to pull up the buggy when needed...
and battery storage if going for more batts for Solar... I have mine on the side.
and yes, CG is a little off ~5" or less, but 550 frame handles it and no known issues...
Hope that helps a little..
