Yes, it was bigger than I expected though. I want another when we get a van!
We just installed on of these heaters (2 kW "Air Snugger" Brand from Amazon. I think we paid $600) in our bus, and it's been one of the best upgrades we've made! Abundant dry heat, thermostat so we can run it all night without overheating, no filling propane tanks, takes a negligible amount of fuel. Best mobile heat solution I've found so far.
