Welcome to the site.
We own a Tour Master, so not the same, however, I can say a few things about Freightliner.
With our rig we had stopped at I think 4 Freightliner service centers for driveability issues. It turns out, all are not created equal.
What you
WANT to do is to make an appointment at the Gaffney SC service/training center and drive on up if your coach is able.

When you call you will more than likely be speaking with Pat. A wonderful lady. Have the last 6 digits of your vin ready and tell her we said "Hi".
This was the only service center that was able to fix our issue. If anyone can, THEY CAN! And these are the ones you want looking into it as they are not only a service center, but the training center. So they know what they are doing for sure.
BTW...You can camp right their at the center. So come in the night before so to be ready.
