Any experience with a gas fire pit?

Well..The wood campfire is getting outdated...smoke and fire danger is not a good idea anymore. So..the new way and clean way is to hook up a LPG camp fire...been looking at the options. Most of us already have an LPG outlet on the rig...so why not go this route? Just hook up the hose and turn it on ...instant campfire clean no smoke or chance to start a forest fire.
