Several great suggestions here. I would also urge you to get a 12 or 20 ton bottle jack, another spare tire(depending on how far you travel), good lug wrench, torque wrench(for lugs), the wood as already suggested, extra water, sewer and electrical connections as already suggested as well along with extra sections of each type hose. The reason for the extra spare tire is with a rig of that length, it will be heavy, and if you blow out one tire, the remaining tire on that side will suddenly be overloaded and damage may be done to that tire as well. This is also the reason for the 12-20 ton jack, lug wrench, and torque wrench.:B
By the way, what part of Georgia???
