I just towed my 7x16 enclosed trailer with 2 Harley’s to Ocean city md bike week.
Mostly highway
I have Timbren on back as my trailer is the v nose style where there is no tongue to use weight distribution hitch so it sags a bit without them.
Total weight probably like 4200 or so now truck has corsa extreme exhaust and that’s it and running amsoil signature series.
I got almost 11 mpg running 70-75 on highway. I did notice that boost gauge was always showing some boost. Oil temp etc stayed very normal oil was like 225 ish in temp
What was odd is the floor in rear passenger side what noticeable hot even the rubber floor mat. So exhaust was hot as shit but nothing else was out of wack. Seems to tow nice. I had a 2018 f 250 platinum diesel. And that was a tow machine. I would not want to tow much more than this as trucks brakes etc are just not like a super duty is. But I love to drive it.
