Who did you try to contact? Here is the name and phone number for the Flagstaff Classic RV service:
or contact sales:
The plant address is: Flagstaff, 201 West Elm Street, Millersburg, IN 46543 Do you mean you have a 8528 IKWS? You refer to Forester, the manufacturer is Forest River, Forester is a Class C RV made by Forest River.
Since you are headed east I may be worth you while to take your RV to the Factory for service. Call them and see if you can get it in to have them remedy the situation. (I don't think they would appreciate a surprise visit) If they can't get to it they can possibly recommend a service shop near them that can get you right in. I know it may not be on your trip agenda but if they can look at it you may have them check any other issues you may have found so far. Trying to get a dealer to look at your situation may be difficult to get an appointment.
