if you do put a good fan in the bathroom, do not have it running with the door closed while you flush the toilet. if you do the black tank will vent up thru the bathroom.

We know that already. Don't ask us how we know. :S

We rented a 27' TT right before we bought ours. It had a very good bath vent. We learned the hard way that you don't run the fan, with the door closed, and flush the toilet. Phew! :)
