Depending on the ground to frame height of your RV (5er), simply put some thick 24" x 24" patio stones flat on the ground, then buy / install some 12-ton axle stands - from patio stones to its steel frame. Install 3 x axle stands down each RV side. On the front, simply install patio stones and power down the front legs. Only take "some" pressure off its axle / rubber tires. Tires should NEVER be lifted off the ground. To view how my TT is stabilized at my seasonal site (to eliminate floor bounce), surf: http://i178.photobucket.com/albums/w...e/100_0696.jpg
Note: As seen within my TT, I used 6-ton axle stands. Next time around, I would use the much wider base / much better 12-ton axle stands.
