Hi Tony. Welcome to the site. Most people I've seen around the campgrounds use propane. Personally, I like to cook over the firepit. That's the best by far but I do all my cooking with propane. I have an attachment (called the propane tree.) on my 20lbs propane tank that I can attach all my cooking appliances to at the same time. It's quicker and with two hungry kids, speed is everything.
