Montana High Country 377FL Dump Valves

[Edward63]

hey all 377FL Owners.

Where are your 3 dump valves located? When we were shopping for the unit all the ones we looked at had all 3 (Black, Grey 1, Grey 2) located behind a door on the DS just back of the back stairs. The unit we oicked up has the Grey 2 valve under the kitchen slideout. Keystone is telling its always been there which is BS.

wondering if they made a production change mid year. Please let me know where your dump handles are. Thx.

We have had 4 Montana’s. The galley tank dump valve has been in front of the tire on all of them dating back to 2004.

My 2019 3791RD has Black and Grey 1 (Bathroom) valve pulls in the convenience center. The Gray 2 pull (Kitchen) is underneath just in front of the slide out on the ODS side right next to the sewer outlet connection.

I have the 375FL, which is the exact same floor plan as yours, including the back door on the opposite side, but no loft and stairs.

The dump valve for the kitchen is located in front of the tires on the driver's side. You have to crawl under the slide out to access it. When the slides are "in" you have to reach up, under the slide-out to pull it.

Here's a photo of where my outlets are. The front one is the kitchen. The back one is the toilet and bathtub coming together. Those valves are located behind that little square black door beside the rear steps.

Mine is really old but the main gray and black pulls are in the cargo bay. The galley dump is towards the back of the coach on the drivers side. I'm not sure Keystones statement is BS.
