I totally understand your frustration.
I went through the process three times.
My dealer was only 60 miles away though.
My unit would work for a month or two and then give up the ghost.
After the last failure I jerked it out and when another direction.
If you are still under warranty then you might ask forest river if they will give you a new unit.
The 600 is problematic and they know it.
I hear that the next model series is supposed to be a better unit.
If you are under warranty you are going to have to play the game.
Believe me, I tried everything I could but they have to follow their policy of bring it in and we will look at it.
I know you are upset but Bob is your best bet for direction on handling this issue.
He wasn't around when I went through my ordeal.
Hang in there, call FR and voice your frustration.
Maybe your result will be better than mine.
