We have a 2000 Jayco Eagle 10...no furnace. We primarily boondock and are considering purchasing a Mr Heater Buddy to help extend our camping season a bit. It doesnt have a great run time off the little propane tanks though. You can however purchase a hose and fitting that will run it off of a 20lb tank. Inside we have the hook up for the stove that we never use. It has a connection that is similar to a air line fitting. Has anyone attempted to or found a connection that will allow me to safely run the heater buddy using this line connected to the 20lb tank? Or is this just a bad idea?
