This is an awsome stand!
I made one a few weeks ago and used it while we were camper camping in a NY state campground.
The only thing I added was a 6" (screw in) eye both at the end of the support, so it would allow me to use my 12'x10' tarp.
On thing I'm going to try, to reduce setup time and reduce transporting footprint.
Is replace the 4 ft bottom footings with 4 -2 ft pieces and mount them as Headchange4u did with hindges.
