+1 for the Camp Chef Explorer 2 burner stove and the pro griddle for the explorer. The griddle is heavy as heck, and is available in 2 sizes. Covers 1 burner or both burners. I bough 2-single burner ones. That way we either have a lot of griddle space (14x32), or 14x16 plus a burner to use to cook something else at the same time.
Concerning the electric griddles, do you guys have more than one camp site? What about a couple 14g extension cords run directly from the 2 pedestals? Or ask a neighbor if you can plug into the 20amp if they aren't using it.
