Congratulations on the truck and the scangauge! That truck an impressive piece of equipment. On our drive it was able to hold top gear without downshifting... right at the shift point of 45 mph, fully loaded to 7100+ lb (truck weigh station verified), into a 30 mph headwind, climbing the Rocky mountains. It gets excellent mileage when you're gentle with it, but will haul anything you want it to.
Oh, and it will "haul" when you want it to.
I earned myself a slap from Wayne by testing that feature the day after the challenge was over.
I had to.. just once!
