I recently noticed one of my neighbors who is a fellow RVer keeps his rig up off the ground while parked by utilizing the rigs hydraulic lifts. I asked him why he does this and he replied that it helps maintain the suspension and tires as well. I have never heard of this and can't find it in any of my RV books and this is not listed in my owners manual either? Can anyone comment on the good or bad concerning this idea?............Thanks..Doc!
