The first question that popped into my mind: Would drilling into/through the frame cause voiding of the warranty on the frame? I used to work for a company that sold truck bodies and we could not drill into/through the frame of these trucks for any reason, everything had to be welded on. On the Home Depot jack: Note that these are advertised as "car jacks" with a 2000# capacity each, a lifting height of 14", and are approximately 5" high closed up. BUT--I'm thinking that they would work with some light mods to them. My ground clearance is such that I would have to use blocks under the HD jacks but that would not be a problem. Hmmm, I may just go purchase one to do some serious "noggin grinding".
