The heritage glen I looked at had the grill mounted on the bumper, even for travel. But I'm thinking it is a different design. This one when the grill is attached seems to stick out further than the one on the heritage glen. Plus the bracket attached to the grill is extremely flimsy. Not sure I would trust it bouncing down the road after thinking about it. It's just a severe PITA to stow it away all the time.
