Filling Fresh Water Tank

[jdhowl01]

I just purchased a 2019 Montana 3811MS. I was reading the sticker on the convenience Center about power filling the fresh water tank. It says to remove the gravity fill cap. Maybe a dumb question but where is the gravity fill cap on a Montana? I thought it might be the black cap on the back left of the rig. But that cap doesn't seem to come off. If that is it, is there a trick to getting it off?

Yes you have found it. Just slide up and it will slide off, or slide up if it has clearance from the belt around the camper. In cold weather it will much harder!
