After a few too many close calls last year with our new fifth wheel and the regular car garmin gps we got a garmin dezl. It lets you put in height length and maybe weight.
It is a much better navigating tool when driving a larger rig IMHO. I still have many other garmin gps’ but they stay home or in the car.
