Me, I like it, if the law doesn't forbid it I'll go for it, now I'll move it back a bit to have the ramps over the flat and level sidewalk, chock rear wheels front and aft, parking brake and go under, I agree that at first it doesn't look right but it's actually quite right I think, the potential forward motion generated by the driveway should be neutralized by the chocks and parking brake, what I mean is the rear tires have to loose grip for the van to move forward while the ramps as long as they are in the flat sidewalk will get even more weight down reducing even further the possibilities of a slide. I think I'll try it next time I have to go under the car, it will be level for once.
