Yep, it's hooked up and has been working for a while, I average 9 to 12 days off the 20 pound tank, I'm as happy as a clam with it, on low it keeps the bus between 68 and 72 degrees, thats with a fan going to keep the air from layering, and with the ceiling vent slightly cracked. No problems with the detectors at all, so they like them too, the condensation level hasn't been bad, even in the subzero weather we've had the last few days it's been comfortable in the bus tho the floor could have been warmer but at -30 or more below, it's understandable. I've gone thru a couple of tanks of gas now and it works great.
