Got the final weights on the unit. It weighs 5680# + 833 for water and 60 for propane and 1500 for the ATVs which gives us a grand total of 8073. The hitch is rated at 12000# with a weight distribution hitch and 600# tongue weight. The tongue weight will be about 800#. Gear ratio is going to be 4.10 which boosts the carrying capacity to 8500# and that gives me some cushion to put other stuff in it since the wife likes to pack everything INCLUDING the kitchen sink. Also will be bringing along some sort of generator for the electric power.

My rear end and front end (4X4) are 3.73 and I will be upping it to 4.10 unless someone things I should go further.
