I was in the Walgreens at 400 South and 500 East in SLC today. They had a stack of 19"x(2)*23"x29"(h) folding tables that seemed suitable for astronomy. Price is $25. The table folds out to 19"x46" and folds-up into a nice brief case like case that is 4" thick that would easily store in a trunk. Black vinyl surface. Made in Mexico. It's a bit low for a chart table to my taste, but is the right height to put two or three gear cases on or one gear case and some charts. - Kurt
