Actually, we ALWAYS drop our '06 Dynasty down when it is in storage, but for a different reason. I do that, because since it was new, the front left corner would slowly bleed down. By dumping the air when parked, I don't have to worry about the coach getting twisted. I just looked at my travel log, and that represents 169 times that we've dumped the air at the storage unit over the life of our coach.
