Hi everyone I’m hoping someone can help me I have a 2017 BigHorn 3970rd. I made the mistake on our last trip to forget the black tank flush on while the gate was closed I didn’t notice til water started flowing from the roof and water started gushing from black water pipe where it connects to the sewer hose. I opened the storage compartment under the fifth wheel where I could see the pipes leading into the trailer and found no signs of damage. We are now camping two weeks later and I’m getting what seems to be a foul smell like sewer gas coming from this vents. I’m not sure what this vent is for and how I should procedure forward. Hopefully I’m not the only one that’s made this mistake. Any suggestion would be great. Thanks
