Hi All - I have a 2014 Bighorn 3010RE with the big 4-door Norcold fridge. It works great on electric and it works fine running on propane as long as the rig is stationary at a campground. BUT . . it will not run on propane when I am towing the rig down the highway. I always set it to 'auto' so it runs on electric when I'm plugged in at the campground and it does switch over to propane when I unplug to leave, but it's always off when I stop for the day, and flashing code 'No FL'. I have tested it by letting it run for an hour or so on propane in camp so I'm sure I have gas (also did run the stove burners to make sure the propane tanks are not empty). I know everything was fine on my maiden voyage but since then it has refused to run when I'm traveling. It's at the dealer now but I thought I would ask if anyone has suggestions. The 3010 has the fridge in a slide, but I don't know if that makes a difference or not. Thanks ! Tim
