2017 Winnebago Destination 39FB 5th Wheel Reviews on RV Insider (2)
Avg. Rating

Wrote a review the other day on our 2017 Winnebago destination 39fb,about the downstairs gray water drainage. It was suppose to say that you have to pull the black water valve in order to get the gray water to drain. When you pull the gray water handle nothing happens..you must pull black water valve then the both drain..does not seem right

We purchased a new 2017 Winnebago 39fb Fifth wheel ..love the Rv with one main exception..you can drain the kitchen gray water without opening the black water, making it hard to use the downstairs bathroom. because you would have to drain black water every time you flush gray water .. Factory says that is designed that way??does anyone else have this problem..Makes no sense why would you have to do that there is even a separate handle for black and gray..
