Looking at your pic on where it comes through the wall....maybe you could release it from the bracket holding on to the wall to allow for some movement? My lines are not the foam filled pipe, but it is the wrapped pipe which is loose in the 4" pipe which I think will allow it to move a lot more. I'm at 95' also, so I think you will be less than the 1' expansion I had. I would prepare for the most movement but would guess that the dealer is right on your application expanding a little. Sorry for alarming you, I just don't want that good work you did twisted up is all.
That sounds like a great idea. I will do that and see what happens.
Thank You for informing me on this possible problem.
