We went out this weekend with my buddy and his new Mammoth. Specifications and options changed before delivery, because he decided on the Onan with two 6v instead of no generator and a 4-battery setup. He has two solar panels and satellite TV on the roof.
Weight with food, gear and Propane BEFORE adding water is 5800 lbs. With full fresh water, it is just over 6300 lbs. His DRW F350 is very close to design limits of the Dana 80 rear axle even though he is fine with LRG 19.5 tires. His concern is excesive wear on the axle at its limit and will be watching his gear oil closely. He has a contingency fund for a Dana 110 swap if analysis comes back with metal.
