I spent much of one day making my pads out of 3/4 plywood. Two layers, 18 X 18 inch, glued and screwed together, with beveled edges (it looks nice), and varnished (it looks nice).
Yes, I put handles on the edge of each pad. The handle make them easier to carry, and provides a place to hook the awning rod in to pull them out from under the coach (and they look nice).
I have been thinking about building another set, or perhaps only a pair, for when the site is very unlevel and I need a little extra height under one or two jacks.
