Well here is my opinion that is just common sense for the question you ask. If your layout has bigger than 22" radius it does not matter because judging by the ES44AC models I am betting it will be fine and if you have smaller radius you have to know that MOST 6 axle diesels by the other manufactures recommend a minimum of 22" radius so just go by that standard for this FUTURE model. You would have to assume someone here
1. Already has one and knows what it will navigate thru
2. Is on the inside of T55 and able to have a pre release unit on hand to tell you
The chances are least likely for even #2 and definitely not a chance for #1.
I have emailed t55 a few days ago with the same question if I get an answer Ill share!
