My Bullet came with the Aussie BBQ Grill, which is very well made and worked excellent when I cooked burgers and dogs. I had no issues cooking on the grill attached to the back bumper. It took about a half hour to put the grill together, but now all I have to do is get it out of the pass through storage area, pull it out of the storage bag (which was provided), stick it on the swing out support, and then quick connect to the gas line port. Looking on this webpage, the grill and mount look to cost almost $400 combined, so it was a great feature that came with the TT.
