There's a big difference in torque output between 4:10 and 3:55 gearing especially with oversize tires.
My ram would probably pull 7700 lbs as well...but from a dead stop it would accelerate like an anemic snail and I'd have to run with the OD off.
This also allows me to watch my gas guage drop like a stone. And plays havoc with my heartbeat anytime I glance at the tranny temp guage.
The comment that the 5.9 gasser makes impressive torque made me snark my coffee.
Not for a truck the size of a Ram.
My feeling is that if you live in a flat area, are only towing a few times a year, can afford the gas, and have a decent or properly modded tranny (forget the bolt on engine mods not enough bang for the buck), you can do this with your ram. Also don't run anything above a 265 tire with your 3:55 gears.
EDIT: If you are going to do any engine mods, buy a tuner like the SCT or a P&G reflash for your ECM. It will remove the torque management and give you some more ooomph. Downside: premium gas.
