Has anyone made their own car ramp, not talking about the ones you drive on to from the front but the ones' who actually you can drive up and have the entire car be lifted off the ground leveled? I'm thinking of making a set of 4 but the more I think the ones for the rear will have to be able to be taken apart by levels, the higher you go the more you would stack, let's say wood...any opinions, youtube failed me on this one, thanks
