I don't think it matters because ride height is the dimension between the axle and frame rail or another part of the chassis that does not move when the suspension is doing its job. It is not a dimension from the coach to the ground. At least that is how I understand it. But you should be fairly level, not way out of kilter. Side to side pitch would matter much more especially if one corner of the coach is lower than the rest since the your ride height will be off and pushing on that corner once your are back on level.
