The t24fqmx looks very similar to my WA2313 (Stealth) in size and weight. I have the Ecoboost not the 6.2, but I absolutely have been impressed with its ability. My trailer weighs about 7800 when loaded for camping with about 1000 of that on the tongue. My cargo capacity is #1765 so when fully loaded for camping I am under tongue capacity, right at my axle capacity, and 100-200 under GVWR.
The truck has plenty of power going up the hills, and the issue regarding stopping is silly
In tow/haul mode I can use the engine to keep speed in control, I seldom even touch the brakes on declines.
I am a former diesel loyalist, but this truck changed my mind. The only sacrifice has been cargo capacity, but with the toy hauler I can just put the excess weight in the trailer, not the bed of the truck.
