Any resolution to this problem via software revision as of yet?

It isn't software.

Allison uses different hardware. We can no longer physically connect to the Allison with the current hardware. If it was software we would have had that handled about three hours after the first transmission was shipped.

First thing you should

First thing you should consider is the overall length of your coach and a trailer that size. You may be illegal in some or many states.

Check the weight of the trailer and all items inside it and then look at the legal tow weight for the coach you purchase.
