I won one at an irv2.com national rally in 2009. It has SST hinges and folds up for storage. It has small locking pins to hold the 3 sides and bottom sheet together when unfolded.
The company that made them, grillguard.com is gone now, I guess the $65 price was too muck for the market.
This one is made for a big grill for home use, but will give you an Idea of how mine was made,
