I would like to lift my 2012 RT onto some rolling supports so I can move it around in my heated garage. The rolling supports are only 2 inches off the concrete floor but would allow me to move it sideways against the back wall (leaving some room from the wall) and still get the wife's car into the garage. I don't have a MC jack and was wondering if I could lift it one side & then the other under the A Arms Carefully! And then slide the rolling supports under the tires? I'm going to put a tennis ball on a string from the ceiling giving me a safety margin so when it touches the windshield it'll be in and still leave some walk around room. Do Able?
