I'll be doing this in an enclosed trailer. I've had it suggested to run a 1x1 inch board thru the spars and hang the walls. The trailer has metal ( I believe they're called E rails) tracking that I can hang them from. I'd use moving blankets to act as a buffer between the wall on the bottom of the wing.
I've also thought about make a couple of shelves and laying the wings flat on some padding and properly secured.
I'm open to suggestions or comments. Thanks
