There are many outstanding features about this type of tow vehicle. Among them, It has the power to climb any grade in the US while towing your travel trailer without downshifting ( unless you come up behind slower traffic.)
400 HP and 1450 lbs of torque.

This unit has a two speed Jake brake. Going down a mountain grade towing a travel trailer using the Jake, you never have to touch your tractor brakes or trailer brakes.

Never again will you fear mountainious driving as so many do when towing with an underpowered medium truck . No more crawling up a grade or smoking your brakes going down. You will actually relish mountain grades in this truck.
