I've got the outback axle on order and will have it installed by my dealer. After 2 years of camping, I know I want higher clearance. Removed the spare from underneath right away, but still drag on my cement barn ramp on the way out - barely but it's enough to bother me. Also bent my jack tube coming out of an old gas station. That surprised me (not in a good way) and next stop couldn't position Bella for a beautiful lake view because I couldn't get the wheel on. I boondock alot and have first driven my expedition into some remote camping areas to scope whether I should try to haul Bella up there - usually the answer is "no." From NuCamp, there is no difference in the build of the body from maxs to outback and I can keep the current tires until I'm ready to switch those out to a 15" wheel and off road tires. BTW - I haven't had any problem in state or national parks with my regular axle.
