Ok I have some photo's of the stands for my camper.
They are 31 inches tall to the top surface of the metal channel. With a 4X4 post layed across they are about 34" tall in the front.
The stand in the back is identical but I only put in a 2X4 so the front is about 3" higher. I also had to level them side to side with some plywood. The Electric jacks foot pads are just lightly touching the wood and provide minimal weaight bearing, but they are so close that there would be no drop if a stand failure occured. I have 12 earth contact points now and with all my strength I cannot budge or shake this camper now, not even a little bit. When walking inside it at this height it's as solid as if it had a cement foundation, including being in the cabover.
I only have 10" of lift and lower range now when I put the camper on and off the truck. This is probably a good system for any camper, but it's especially good when you have a very tall truck.
I had a little rubbing in the front on turns under compression but I did a little trimming and that took care of it. I'm running 315-75-16 Toyo Open Country M/T with 16x8 Eagle 187 wheels. The tires are E rated with a 3860 load rating. Nice tire.
i run a 12/33/16 (305/70/16) toyo e range on a ford (no lift) it dont handle any differently than it did b4 the taller tires. i agree the ifs system will b the weak link. sweet looking truck though. go with a light weight pop top camper, and you should do fine. get the strongest helwig sway bars you can get, airbags or timbrens if you can, stiffest shock possible, you will do fine!
I too run a 2 inch level kit with airbags.
I like the set up, since it is not too high and does not give me any problem s 4x4 ing and any arkward off camber situations.
I run 255/85/16s on stock rimms.
