I wanted more 'stabilization' than the factory front and back stabilizers were giving me. I bought a set of scissor jacks and found two problems right off. The propane gas line was running on half the frame rail and the jack would sit offset and not imo be very sturdy with only a couple of self taping screws to hold it on. The second problem was that my side skirts dropped down to far to be able to jack (screw in) the jack up as high as it should be to the frame and not flop around when traveling. Solution to me, Camping world sells a quick release 'plate' that screws to the frame and allows the the jack to be quickly pulled off and stored away.
I did not buy mine from this company, it is only used as an example:
