I have used this truck like a truck and it has acted like one. I have wheeled it some in mud sand and snow, and it has gone everywhere the BFG All Terrains would let me. I have slotted and drilled disks in the front and a 5 speed, so a few less things to worry about.
I have worked the hell out of this truck, and it always performs. Towing my Jeep or Ford around, it never lacks power. Hauled a Harley in the bed and a boat in tow this summer from Oregon to Arizona, and it did awesome.
A few months ago I did a scrap metal run 100 miles to Portland. It pulled all the hills at 50-55, got 13 mpg, and crossed the scales at 11,200lbs combined. Ha ha, Dodge rates this rig for around 4400 pounds and the rig weighs about 4500.
I love the little truck. I will be getting a cummins some time soon, but until then, the Dakota gets it done.
