Marooned

It all started on Monday when we unhitched and drove from our boondock at the top of a mountain (down a gravel Forest Service Road) to the visitor center at Glacier National Park. Once at the visitor center, we heard a hissing coming from our back passenger side tire. A huge screw had imbedded itself and our tire was quickly letting the air out. My husband plugged the tire, so the air was leaking more slowly, and we limped to the nearest town. The tire was unrepairable and required that we buy four new tires (the joys of AWD). With the spare tire on, we limped back to camp as there were no tires our size to be had in the town or surrounding area. With our tires a week away, unable to leave our campsite and with limited water and food, I keep hearing about wildfires not too far away in Idaho and Washington and looking around at the kindling pile we are sitting on. My question is this: if there is a fire on or near our mountain, would it be crazy to attempt to tow our Airstream out on the doughnut? I mean, this would be last-ditch attempt to save our home. Has anybody ever tried it and what was the outcome?
