All valid points, I hadn't thought about the angle when you come off a driveway, that is a valid concern as it's pertty low as is, in fact I will probably need to move the plate holder so thanks for pointing that out.
Yeah, this model Voltage has an 11 foot garage, which holds my Harley and two bicycles plus all our other crap pretty well. But it would be nice to be able to hang the bikes out side.
I have also seen a different toy hauler that had some extra gear welded onto the ramp, in that case it was to make it less steep (owner was in a wheel chair) so he had short little legs attached to the ramp, and a second fold out ramp to make getting in and out easier. I looked at that and though maybe I could weld on a couple of rails that I could then hook the bikes to (similar to the rack you see on top of cars).
Not really necessary, but I am notorious for always wanting to modify stuff.
