Do you run the heater out of the bag hanging off the spare tire? Just tuck the heat tube inside the rig?
Andrew, I do not run the heater in the bag, would have visions of it melting through the bag in the middle of the night...lol I remove it and set it on the ground tucked under the back of the Jeep to keep it out of the majority of the elements. I leave the flexible intake air hose and filter attached and folded up the back of the unit when putting it away, The exhaust is bent to a 90 degree and I slip it over the fitting on the heater with a hose clamp, remove for storage. I tried one of the amazon slinky hoses for supply air, but did not like the smell that came out of it, was not going to last long due to how thin of a material they use, and unless stretched out fully the inner diameter was so restrictive it caused errors on the heater. I bought a silicone hose that is flexible but does not collapse or have any slinky action. We cut it to a length that will reach from ground level into the tent door, which also allows it to enter the rear of the annex and extend to the middle under the table by the ladder which keeps both annex and tent warm.
