So besides a little bit more ground clearance and a bit more cargo capacity, are there other advantages to getting a camper with a 3000lbs (vs. 2500) axle and 14" (vs 13") wheels and tires? I am considering a new Aliner and their off-road package is available for a reasonable price. It just includes the axle and wheel/tire upgrade. Do bigger tires help the camper tow any better or track straighter or improve the ride in any way? I like the idea of the heavier axle and bigger wheels/tires, but will probably never go off-road, so the extra ground clearance does not really matter. Will the same model camper with the addition of the off-road package make any difference in regular use?
