I use two eight ton hydraulic jacks for the stabilazation under the front axel. Initially, I level the 5r, then position (lower) the electric rear stablizer (raising the rear about 1" to 1-1/2", then put the bottle jacks on blocks (3 blocks used for 15" tires), screw the center post up to meet the frame and then lower the rear stablizer about 1/4" to 1/2". If needed I could jack the hydraulic jacks up a bit but staying in one spot for close to a month I think it would bleed minimal pressure. And, yes I also use it for removing tires.
