Mr. Heater “Big Buddy” Indoor-Safe Portable RV Propane Heater (Grey)

The Mr. Heater Big Buddy Indoor-Safe Portable RV Propane Heater is  the most Popular Portable Propane Heater in North America. This patented radiant 4,000-18,000 BTU Liquid Propane heater connects directly to two 1 lb. cylinders and is the perfect solution for heating enclosed spaces like cabins up to 450 sq. ft.
