When fall arrived in the Tetons, I found myself facing the harsh reality of freezing temperatures. Nights dipped into the 20s, and my van became an icy box by morning. With just a sleeping bag and some sheets, I woke up shivering and surrounded by frost. Running the van’s engine all night for heat wasn’t an option, so I needed a solution fast. That’s when I discovered the Mr. Buddy Heater.
I drove to the nearest Home Depot, grabbed a Mr. Buddy heater and a small propane tank, and hoped for the best. It worked—kind of. After years of living vanlife through all seasons, I’ve learned what you need to know about using a Mr. Buddy heater to survive cold nights in a van.
