We have the Coleman Roadtrip. We're limited on space so we never bring it camping, used it for grilling out at our apartment. Works great, but it doesn't fold flat to the ground so it is hard to pack. If I got one again, I'd get the Roadtrip LXE . My father in law has it and brings it along. It has two burners for more control, side tables for prep, and you can change out the grate for a griddle.
Since I'm limited on packing space I just use an over the fire grill grate. Works great, and it's cheap. The more expensive models come with a grill and griddle. over fire grill
