well, last time we went off roading, my father plowed the axle into a bolder doing 30, so now we need new shocks, we do some off roading (not much) and we start doing a lot of towing soon. so what do you suggest? we need the entire set for under $350. (so we are not looking at state of the art) but is it possible to get adjustable air shocks for at least the rear for that price? even if only for the rear.
