Winnie adventurer water tank

On our 2007 Suncruiser, (same as Adventurer), it is in the first outside compartment behind the entry door on the curb side. It is a 3/4" ball valve with a large handle and an elbow going down through the floor to underneath the coach. If all else fails, consult the manual for your coach. Good luck-- Mick

Ok thanks for your replies, but nothing yet

On our 03 the tanks are visible inside compartment behind entry door. Quarter turn ball valve at bottom of tank.

And thoroughly underneath his RV.

I’m certain billy checked all his compartments.

Check all your compartments. On my 06 is located midway back on the curb side in a storage compartment.

The Winnebago site was not helpful? I’m surprised after looking it didn’t assist you.
