Hi Guys.
I drive a 2016 F350 dually with a 6.7 diesel pulling a 20000 lb fifth Wheel. average 7.5 mpg.
Going up a steep hill slows me down to 40 mph.
Looking at buying a 2018 Freightliner Cascadia with a dd15 automatic 2.47 differential tandem axles. Will remove the rear axle and build a bed. What do you think.
