For anyone wondering gas vs diesel heres a little report. We've got a 2018 powerstroke dually and a 2019 F350 6.2 L gas single wheel with a Deweze bed and feeder on it. The dually was in the shop this week and we had to go get 20 bred heifers in Lorena, Tx which is 220 miles one way from us. It took 2 trips but we made it just fine. We pulled a 28' cattle trailer and hauled 10 hd at a time. Truck got 7.5 mpg down there and 6.5 mpg loaded on the way back. This was doing 65-70 mph. Truck pulled great on the flats but the trip was rarely flat. The transmission kicked down into 4th on most hills and 3rd on some but trans temp never changed. This truck gets about 9mpg daily driving around here so I thought the fuel milage was good. I figure the dually would've avgd 10 mpg so we only spent maybe $30 extra in fuel. Overall it was a good easy couple days driving. The 28' cattle trailer is a triple axle and weighs around 7,500# and these were big heavy bred Brangus heifers that probably weighed 1,050# or better.
