Since it is 4wd and work based, I would look into a diamond tread or sheet metail belly pan / skid plate. I would also look at the area in front of the front wheels. Huge void, that are begging to be blocked off.
There is a lot of real estate under that truck. Skid plates would offer protection offroad, and smooth air flow.
Where is tire pressure? Many of the HD trucks have tires that can go as high as 80lbs.

It's 2WD so no front diff, but the underside does make a lot of drag I'm guessing. Tire pressure is about 70lbs.
I did a little run yesterday about 40-50 hwy miles. This was the first test I did since I took the rack off. My scangauge is calibrated pretty close I think. It usually reads 19-20 average for the hwy. Yesterday it read 24. Some of that was probably driving style changes. I'll have to wait to get back down to empty and hand calculate it to see what I actually got.
