Unfortunately (in this case) it is a 4x4. The bed (height of 34")itself, I think is low enough, the problem will be the clearance on the top of the truck sides to the bottom of the hitch pin arms on the trailer as they hangs down the farthest? Looking at Alf's (thanks for the info) picture it may be that I could get away with raising the height of the trailer up by jacking the trailer up, then blocking up the springs so that there is no more sag, letting it down and then bring it home. Then just properly by doing whatever is necessary.
My truck has the older style of box so the sides are not as high as most if not all of the newer ones. I was vey surprised when told that I would not be able to tow it with my truck due to clearance issues. Roughly figuring and measuring makes me believe that I will be able to tow it home if I set the 5th wheel hitch on the truck and trailer at its lowest or highest setting. The trailer will not be sitting at its optimum level but I think it would be doable for the 5-6 hour trip back.
I'll know better once I see and measure it for myself - providing the trailer is as advertised. No mice, water leakage, mildew, body in good condition, everything working, etc.
Does anybody have any other or better suggestions, concerns or comments that may help?
Thanks in advance
