Trailer advanced coupling workflow
Target behavior: back under the trailer with ATS Advanced Coupling, let ATS latch the kingpin, then have HaulTools immediately recognize the connection and prompt the driver to exit and finish the physical trailer-service steps.
- Legless trailers skip landing-leg interaction automatically.
- No extra in-cab T press after the kingpin latches.
- Walk Mode handles air/electrical line connection as the next required step.
- Trailer-specific unhook logic keeps legless and standard trailer workflows separated correctly.
