I purchased one of these grills over the weekend. We got back to the RV and I went to assemble it. I found that not all of the holes had been drilled and some hardware was missing. As the campground was only two miles from the C.W. store we drove back to exchange it. The store had 2 grills left. One was in stock and the other one was a display model. Both had cracked or broken housings. I decided to keep the one I purchased first and C.W. gave me the missing hardware from one of the other ones. I took the grill back to the campground and drilled out the holes (6). The smoker plate was covered with a heavy coating of cozmoline (sp). I got the grill assembled and fired it up to burn off the cozmoline. It lit and obtained a very high heat. As I was not ready to cook on it I allowed it to cool, about 5hrs later I tried to relight it and the regulator would not work correctly. I suggest you inspect it then check it out at home before you go out to use it.
