The Tank Caddy solves a very common problem: transporting heavy, unwiedly propane tanks safely. Everyone knows that the most difficult part of owning and using a gas grill is handling the tank. It's a drag. As if the tank isn't heavy enough empty, when it's full it about rips your hand off as you try to carry it from the store to the car and the car to the grill. Oh, and how about that uneasy feeling you get when you make the turn out of the store parking lot and you hear the tank roll over, careening to the other side of your trunk. Handle snaps into place when upright or folds away for tank to nest horizontally in rear of vehicle. Rugged double wall construction won't chip or rust. Comes fully assembled.
