turn off OD?
what is the weight when I should be concerned about turning off my OD?
had my owners manual stolen(of all things) when my truck was broken into so I cant look there and I haven't found a definitive answer anywhere else yet.
truck is a 99 v10 auto 4x4. im towing a travel trailer that weighs 3500-4000 loaded. I know for serious hills, up or down to turn it off, but will it hurt anything on mostly flats to leave it in OD?

No, it will not. And isn't it an automatic? Won't it downshift automatically going uphill if it is needed? When I was towing my 9,100 pound travel trailer I didn't turn off the OD going uphill. The computer did a good job of deciding when it was time to downshift, and I let it do it's thing.

This is good to hear Mark, I've always been afraid of damaging something. I got a 9000 lb.travel trailer I've always towed with OD off except on long down hills. Might get another .5 mpg.
