We had the Roadtrip, but man I hated that. If I want to grill, I don't want it to be on a flat non stick surface with slits in it and it was SO HEAVY and I hated cleanup!! So we sold that, and went back to our old gas Weber Go Anywhere grill, and a small Coleman camp stove. I hardly ever use the stove outside, so it's just stored. Plus, we like to grill over the fire if we can and use disposable grates that I pickup at Daiso (a Japanese dollar store).
Basically, what I'm saying is, I don't like grilling on those non stick surfaces, more on a grill and I prefer to have my stove separate, even though it's two different things to bring.
