will never go back to propane

Diesel is the way to go for sure. We had a propane heater for a while and we weren't happy with all the condensation so someone suggested to buy a diesel heater. We found Expedition Upfitter through google and bought this one with the manual controller. It's been perfect for us- no complaints.

Put the heater in my Mercedes Sprinter the other day. It started right up and produces an impressive amount of heat. I'm looking forward to lots of warm nights.
