thanks for the input. I might have to try that. I think I'll first make sure I trim any of the hanging plastic off. Then I'll adjust the springs (if they are already on their lowest point). If that's not enough, I may try just the one 2x6 I had before under the ramp where the tires drive up. If that doesn't work, I'll either bite the bullet on the battle armor or try the ramp you are talking about. I'll probably lean more towards the bracket lift as having higher clearance all the time can only help and then I won't have to carry around the wooden ramps.
Do you have stock size tires? if not, does any calibration need to be done with the computer if someone were to go up slightly in size? For me that is a ways down the road, but thought I'd ask.
