Take a hike Casey
You are being rude.
This board is not an engine for immature jackasses such as yourself that have nothing better to do but hang around and burn the other posts.
Fact of the matter is, you could jump a truck going over a kid at 5 MPH, as long as the jump were big enough. In this case, it was 1/2 sheet of plywood, at about a 45 degree angle. The point that was being made was that with that type of angle, it has a flat landing from a high alititude and held up perfectly.
What you dont know, is that my truck weighs 10 pounds, and even at 15 MPH directly in to concrete, you are going to jack something up (in this case, it broke the front skidplate). If you dont believe this will do damage I will have you over sometime and run it at the measly 18.1 MPH in to your shins.
Until then, go play with your little jr. high school buddies.
