Just curious, if you put the wheels on wood blocks (up 8" or so as one poster mentioned) wouldn't you also need to put blocks under the jacks? If so, wouldn't the weight of the rig break the boards? On my DS, I can raise/lower both front jacks, both rear jacks or both on left or right side. I cannot adjust jacks individually. So, if I were to drive up on boards for one tire, the distance from rig to ground for each jack would be different. Sorry for rambling...just trying to ensure I'm prepared in case to situation arises.
