I thought the OEM grill was the biggest disappointment I've ever experienced in a grill and after the first use put it back in the bag and tucked it away to never use again.

So what I did was buy a CampChef Explorer 160 2 burner stove and the Grill Box 30 14" where it actually gets sear marks on your steak and cooks it properly. It uses infrared heat to cook, not flames.
That OEM grill was garbage IMO.
All this can be run by a stand alone bottle or if you want like I did, ditch the stove hose (which had a regulator) and do a mod to tie into the trailer supply, where you don't need to get a regulator.
