[grill-n-go]

We use the smaller model of the Buddy Heater with a seperate 20 Lb bottle and a 12 Ft. hose which lets us keep the propane outside and bring the hose into the trailer through a small gap either by the door or one of the vinyl flaps depending on where we want to place it. With temperatures outside as low as 40 degrees F we've never been uncomfortable. For sleeping purposes it's placed by the fridge and pointed towards the bed area. I don't like the idea of placing a heat source in the hallway itself nor have I ever felt the need to do so.
