I have a 2020 F350 ,crew cab ,long wheelbase, 4 x 4 with 373’s, 7.3 engine, 10 speed
I have about 6100 miles on the truck , I have a towed a flatbed trailer with a 1800 pound zero turn mower on it or a John Deere 1025R tractor with loader and backhoe,I was getting 12.8 MPG,I recently towed a 2003 F250 with a 73 diesel, 4 x 4 crew cab and got the same 12.8, All of it has been flatland Towing,I like the 7.3 and 10 speed
For what I’m using it for, I am told the 6.2 performances similar but at a greater gas burn penalty
