Arctic Fox 1150 on F350 DRW diesel?

We have a 2008 350 dually diesel extended cab with an Arctic Fox 1150 and are completely satisfied with both the truck and the camper. Both the 1150 and 1140 have their advantages, we wanted the extra closet plus did not want the stove next to the dining area, ours is also a dry bath model by choice. Our truck is RWD and is not rated for a camper specifically to not have limitations - it was ordered with the heaviest axle ratings and 4.10 gearing specifically for camping, we also tow a 4,500# boat or our motorcycle in a trailer using a Super Hitch. We have air bags (use about 40 psig with camper) with on-board compressor and separate adjustment for each side. I am installing Rancho 9000 for this camping season as the truck has 20,000 miles on it. I also will be installing Timbrens, not for load carrying, for a softer stop of the axle on a large bump, the factory bump stops are quite hard. We travel with full water tank and have no issue. From a certified scale the truck alone is F=4,250, R=3,480 = 8,000#: truck & camper (no water) F=4,460: R=8,240 = 12,700#. Great camper, great truck - hopefully you will find what fits you the best, good luck. Happy camping!!
