No geometry problem - simply a paved driveway that's seen better days. It was by no means a level surface when I took the measurements, frost heaves and the effects of several large roots under the driveway...

I'll find the nearest granite countertop dealer, have them lower a slab to the ground, then drive the truck on it. That should allow for accurate measurements <img src="/forums/images/graemlins/cheers.gif" alt="" />
