With the cold weather months upon us here in the Pacific Northwest, I pulled my Mr. Heater brand Big Buddy portable propane heater out of storage and hooked it up to the quick connect propane line that I installed in the van last winter. If you are going to live in a vehicle through the winter, a heat source is a must. I have slept in my van through nights that have been below 22 degrees F and stayed perfectly warm with the top popped while my Big Buddy heater burns on low through the night. The nice thing about having the Big Buddy model, is the capability to have it plumbed into the existing Westfalia propane system via a quick connect propane line that is plugged in to the non pressure regulated port on the heater. This allows you to use the higher capacity onboard propane tank without using up the expensive 1 lb disposable bottles. Also the Big Buddy has the capability for hooking up two 1 lb disposable bottles in the case where you must run off the bottles. While running on 2 disposable bottles, the heater will burn on low all through the night. I have found that running off 1 disposable bottle on the smaller Mr. Heaters will not get you through the night. Here is a quick video review of the heater. This heater is a MUST HAVE in my VW Vanagon Westfalia. Enjoy the video.
