With 3,000 miles on the truck, it was time for the first tow! Hauled the TJ from Grand Jct to Ephriam and back, which is around 500 miles round trip. The drive across 70 has some pretty long climbs and descents, as many of you know. The truck tows as you'd expect, like a modern & powerful big block coupled with a impressive 10 speed transmission. I know this won't make sense if you haven't experienced it, but the torque and HP of the 7.3 make the truck feel very capable hauling the Jeep. The TJ & trailer is about 6,200#'s, a fair amount of weight.
When the 10 speed transmission downshifts on the hills and the 7.3 starts spinning higher RPM, it pulls hard and sounds incredible, for a stock truck! It has no issue accelerating up hill with the trailer hooked up either.
I reset the MPG when I left and watched it thru the trip... lowest I saw was 9 MPG on the long climbs and highest was 11, average for the trip after 500 miles was 10.5 MPG. Overall, I'm very happy with the truck and towing the trailer on the freeway. It feels very planted, rides great with the trailer in tow and has more than enough power at speed.
