Currently have unrolled both segments, with front part on that overhead bulkhead are, across the pipe rail holding the bed-area curtain, and on to 2 separate "spring tension bars" . We can both walk under the pads with room to spare, and they can be detached easily. Haven't got the little road loop on them yet to check the vibration "will they STAY UP?"
I burned out of the constant migration of tekkie trobles/revised business models of various 3 or 4 photo servers I just abandoned the time/effort to use them. I'm not a yahooer or signed up for any fb/twerking/whatever the other stuff is called. A Luddite can go only SO far & that's it!!!
