Is it possible to add a bedroom roof vent to a 2016 21FBS? The roof and ceiling appear to be a unique design and I have seen someone post about Heartland stating a bedroom roof vent cannot be added in the first 2 feet behind the front cap. I was just hoping for some clarification on this issue. We have experienced some humidity (front wall between the nose cap and mattress) and heat issues in the bedroom and I was just interested in others experiences with this model TT. Thanks!
