My XT276 came with an included grill (and storage bag) that mounts on the factory installed bar on the side of the camper. It works very well so am pleased. I did buy a 10' extension LP hose so it can be set on a picnic table too.
I've found most items for a camper as also available using a google search or ebay or amazon, etc. and often at a more economical price than from an RV dealership.
