I liked the idea of these jack foot pads for stability BAL - Innovative Products for the RV Industry
but could not justify the price.
Solution was to make my own. I ordered some 9x9 black king starboard in 1/2" online for 40 bucks. Countersunk the screw holes and bolted them up to the existing holes in my scissor jack feet with stainless bolts. Worked out great and now the pads line up size wise with my leveling blocks. You loose about an inch clearance while retracted. We will see how they work out but turned out pretty darn nice for the money.
