I have a Starcraft Comet 10RT. If I ever need to change a tire, I'll need a pretty tall jack. The manual says not to lift by the axle, but use the side frame. The low point on that frame is 22 inches from the ground. I suppose I could put several blocks of wood under my Grand Cherokee jack, but I wondered what you all use? Will a 30" scissor stabilizer jack work for tire changes?
