I'm going to stop measuring when I am tired. I had been working most of the day (and had not been feeling well to boot) when I measured the frame (at least 5 times) for building a cab dolly, and then measured 3 or 4 times laying out where to weld the support arms on the dolly. Still it was off about 3 inches. At least it was easy to fix. But I could have sworn I had it right, I had checked it so many times.
