My fifth wheel hitch is at the bottom but my pin still has another set of holes for further adjustment. I decided to not move my pin for two reasons. First, the weight of it is problematic for me. Second I took my coach and weighed each rear axel seperatly to see how much additional weight load was being placed on the rear axel due to levelling issue. My rear axel was carrying 800 lbs more then the front and that's ok by me, it just means I rotate the rear tires to the front every year.
As for the adding hight to the trailer that's an option but not needed for me. My coach is 7" from the truck bed rails with 15k total coach weight. It's slightly nose high but it works for me. Each set up will be different but it sounds like you understand the scenario. Another option but expensive could be new tires and rims. I have GY 614 g rated 16" tires so take a look and see if larger tires could help shave an inch off. Good luck
The King Pin is very heavy, one would need a Fork lift or a Front end loader to bring it up one set of holes.
Since the dealer installed the pin box, but under inflated the airbag, he can do it.
Ones this is done and the trailer still is high in the front, what about drive with KingAir under inflated ?
When we original drove the trailer home (450km from here) it seems to drive OK to me. I did not find any difference driving fully or not fully inflated.
I had one blowout (expensive repair) on my old fifth wheel and the extra load on the back set of tires would worry me.
Let's see what it looks like ones the pin box is moved up and see what is the next step if needed
