TP: re: "When we set up for the night, we slide the angle into the supports as we unfold the jack-knife. The couplings make a nice solid base for the supports. "
thanks for the excellent description!!!
I have since fabricated a version that seems to be doing the job.
Don't know why ~I~ didn't consider this design in my unbounded dithering the last 12 months or so....I was trying to cobble a serviceable ledger-support along the edge of the dinette seat pods. Never came up with suitable hardware.
This simply pylon design is very promising, and we're planning a trip soon to visit the Oregon Coast whale migration watch.
Thanks again, and Merry Christmas to ALL!!!!
