The diesel exhaust from the Aqua Hot does have a distinctive smell. But it seems to get milder after some use. If you can't see the exhaust, then it is probably not burning rich.
The exhaust odor is an easy trade-off for the advantages of the Aqua Hot. I wouldn't buy a coach without one ever again.........
