Welcome to iRV2, jsierra.
I'm sure some other Winnie owners can help you out, so ask this question down in the Winnebago owners Forum. They will need to know which model you have - the dip stick location varies.
The Winnie forum is here:
2004 American Tradition; 2014 Buick LaCRosse
Homebase in the Ocala Nat'l Forest near Ocala, FL
