Maybe with a snowmobile trailer................Try it with a Gooseneck full of steers.

Main problem with the NV, is unlike an Auto which knows when to downshift, the guy in the seat doesn't think that way and problems start. Most of the NV problems started because of an engine called a 5.9 Cummins. You have so much torque it is possible to pull hills in OD which a huge load, the engine has so much low end it wouldn't quit, and common sense tells you that a rinky dink pickup tranny in OD behind that engine which has a much larger transmission behind it in Commercial applications is gonna be the thing that will break.

Anyway, I don't think an NV would mind running in OD towing down the fairly flat 4 lane black top...........Its the instances I mentioned above where they flake out.
