When I recently picked up our TT I was surprised to see that it didn't have anything to prevent bottoming out. All our previous RV's had either a "V" shape angle iron welded on or skid wheels of some sort. My concern would be when you drive over a severly crowned street or something like that. My old TT would really bottom out hardand I sure wouldn't expect the flimsy bumper to bear the brunt of that. Hopefully these Outbacks are enough taller that this won't be a problem. Anybody encountered this problem or taken steps to avoid it?
