I agree. The transmission in the 6.0l and 6.4l trucks (5R110) is just about bulletproof. The turning radius in the 2005 trucks are a lot better than the earlier trucks. I think that the later trucks are even tighter.
I had a 2003 6.0l with the same 5R110 transmission. I used to pull hay trailers with it quite often. I have a 35' gooseneck, and i loaded it with 20 5x5 round bales. GCW was 39500 lbs. I towed a many thousand loaded miles with that kind of load. The transmission was great. The engine was also great, when it worked. I had a love-hate relationship with that truck. The later (2005-2007)6.0l trucks had much better reliability as compared to the '03 and '04 trucks.
The 6.4l trucks (08-2010) are pretty sweet. They have a stronger version of the 5r110 transmission, and they make a little more power from the factory. Far more reliable than even the later 6.0l trucks.
If you are looking for an older truck, the 7.3l trucks are very reliable. As long as you keep clean oil in them they will run for ever. Their transmissions are not as good as the 5r110. They are alright, but just not as tough as the newer ones.
Welcome to the Org, BTW.. Sorry to hear about the circumstances of your new truck purchase.
