I'd like to use my ramp as a patio. Is it safe to just put some jacks under the rubber bumpers? I load 980lbs bikes with that ramp so it should hold 3 or 4 adults, no?
I think if I was going to do that I'd run a 2x with carpet or something on it to prevent scratching, across the door from one jack to another just to give the middle a little support. I would also run it across about 2ft or so from the end and not all the way out to the rubber bumpers.
