Sewer Gas Problem with Thor 34E
The problem is not with the forward washroom which has the kitchen and bathroom sink go into the black tank. It is also not the back toilet, it is the back grey tank. They completely forgot to put the vent valve on the back sink. You can see where they started installing it but did not screw in the valve. This is the third motorhome we have owned and must say that THOR has the poorest quality control out of them (Adventurer and Coachmen).
