Here is how to hook up any Coleman high pressure grill with regulator to your low pressure propane quick connect found on most new travel trailers. You must remove the pressure regulator at the grill as you already have one at the tank end of your RV.
Sorry – kept calling it an XLR grill in the video but it is a Coleman LXE grill. This mod will work with all Coleman high pressure grills. Also my boy was holding the Flip camera and was a little shaky at times – my apologies!
