We got whatever make of grill Sunline was supplying with our 264SR. My wife and I agreed after the first couple of uses that it was totally not worth the money. We saw no safety concerns but, like someone already said, it took up too much space, was too hard to clean (if you want to store it anywhere in the trailer without smells), and in general didn't work very well. So I scrapped it, literally heaving it into the trash, and made a small, weatherproof table top that I attached to the frame that held the grille. The table is MUCH more useful, being beside the door and all.
By the way, I saw a *really* nice 'Suburban' exterior 2-burner stove on the side of a pop-up trailer at one of the shows. I'd buy it in a heartbeat to heat water for stuff outside. This burner had a neat high density type molded foam base thing on the bottom with some small pocket areas to hold utensils, and a lid like a coleman stove on the top so you could use it as a table. It hooked onto the same small rail that's on a Sunline for the standard grille and the gas was low pressure and would connect where the standard grille did also. HOWEVER, I could not find it anywhere on Suburban's Website so I think it was custom made for the pop up manufacturer, which I forgot to note down. If anyone has any info on this, please advise. Thanks!
