Correct me if I'm wrong... if your jeep has an Overdrive. you want to stay shifted in direct drive when towing a trailer and or offroad and or otherwise on the skinny break stuff pedal. I'm curious where the line would be for able to engage the Overdrive for say 2over on a hill. Empty m416 maybe? Background: Jeep has peppy v6 and 5.38s Trailers are a 1980s coleman popup at maybe 2000lbs with brakes that I want to get working, and a M416 with say 800lbs (figure 1500lbs total no brakes) I am about to let the 180hp jeep do all the truck stuff since the wife likes the 280hp family wagon.
