Is anyone taking their Model X off-road? How are you finding the experience of off roading? a half dozen or so times a year, we head up some back roads camping. The majority of the road is just gravel/dirt with some ruts, but the last 300' are pretty rugged. I assume I'd set the suspension to very high and hope for the best. Would I have to worry about a sharp rock damaging the underneath or is it pretty bulletproof? How about dirt and mud from such an excursion? Finally, has anyone experimented with more all terrain tires?
