Well it appears they have reversed the denial based on rust, my only issue now is it still does not appear I have got any progress in getting things repaired. They called my repair shop and asked some more questions and now when I called in today was told they are waiting on my repair shop to call them back. They also now have mentioned they may not cover all cost of repair so really confused now.
I now have a call back into repair shop, hope to get a positive answer this week on getting repairs done as I really would like to use my motor home, only issue now is it has been sitting for months now unused.
