So, is there a safe method of fetching a 5-gallon propane container in my SUV?
Sort of, yes. Open all the windows, and (here's the biggy) DO NOT SMOKE OR LIGHT A CIGARETTE OR CIGAR!!! If it is too hot or cold to have the windows open, do it anyway. If you just absolutely HAVE to have a smoke (been there, did that), pull over and do it outside the car.
A similar occurrence happened in Great Falls, MT many years ago. A guy had a 20 lb. cylinder filled, loaded it in the back of his Jeep Wagoneer and headed for home. On the way, he decided to light up a cigar.
BAD mistake, with similar results!
