thanks, i can see how it would be challenging by ones self especially with a floppy tape measure. i'll try to bring a rigid tape with me on Monday.when I fly, but it's good to know at least a couple of the dimensions are accurate-ish. it seemed like the source of most of the probelms was the 22" dimension, i'd expect basically every roller would fail if the if the 14" dimension was off in the engineering.
