I just got back from a 1200 mile round trip towing a little over 10k with my 97 E350 powerstroke. 37s and 4.56 gears with a 60hp tow tune from Dp and new swamps stock injectors. It pulls good but you have to be patient and I had to pedal it the whole trip to keep it under 1200. never drove over...
Mobile is an understatement! They are all running, climbing and daring each other to climb this and jump off that. They are 16 months now. Been a long but fast 16 months for sure.
