I carry several pads made from 2x stock sandwiched between 1/2" or 3/4" plywood with a 45degree angle cut on one end and a hole on center on the 45degree edge. The hole servers two purposes. 1. I use it with a hook on a pole to remove the pad from beneath the mh. 2. If the pad slips when I try to drive onto it, I place a knotted rope through the hole, align the pad to the tire and drive over the rope, which secures the pad and allows me to drive onto the pad.
