Yes L43 Dean, it IS possible!
Spied in Boulder. Snapped some photos and left a note. No call or email yet, but fingers crossed. Did not have a decent camera and cell phone photos are terrible to see what was going on. But didn't seem like he needed a sub frame, bed rail adapters or anything. The 'Nest was sitting right on the bed rails as far as I could see. Very clean installation, in fact it was a very clean 'Nest.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
