On my 2005 Hawk I used three cable Jacks; two on the heavy side on one on the light side. One leg pad was already slightly crushed when i got the setup so i made sure to always position it ahead of the tire and it did get run over each time. It was always sketchy. My current Hawk has corner brackets and since I have three vehicles I rarely take the camper off but when I do it is very solid with four corner jacks.
How about getting rid of the tripod legs for the two jacks forward of the tires? A flat plat and welded tall sleeve. Easy to drive over. Example would be an umbrella base as shown in the pic.
