Alright I have an 2011 F-350 with a 6.2 which I will use to tow a 3795 Cyclone. I had another post going about gear ratio and power. I don't know how big the 2985 is. I am not trying to prove anybody wrong, but I hope my truck does okay so I don't have to go diesel. My 03 6.0 diesel gave me problems, turbo went out and replaced two trannies. Plus it was slipping again when I traded it in. I could have had a lemon but we use them at up here at work, so I have some inside on them.
