Just out of curiosity, how does the truck do with that load? I come from a regular titan 5.6 and towing a 7k lb camper that truck hated its life.
The DI 5.6 Does great. I don't have any complaints about power or braking. We just towed again this past weekend and we were on flat ground for a good leg of the trip and I reset the trip meter once we got on the highway. At the next gas stop per the computer we were at almost 11mpg too!
Driving in the mountains we may scream at times up to 5krpms (we did a 7% grade for 7 1/2 miles maintaining 65mph and it never went over 4k rpms) but it's not too common and that is just to maintain 60 to 65mph otherwise she hums along under 2k rpms.
In that video it was just me and my mom in the truck. We were probably around 9500 to 9600 total in the camper. We had a few things in the back seat of the truck too. Not a whole lot.
