Pickup caps and wind resistence.
I was wondering if you might get better gas mileage when towing a travel trailer when you have a cab high of higher cap. I have a hard flat cover now. Has anyone had any info? or comments.

You will gets lots of opinions... including mine. Yes a shell will improve air flow and to a small degree mileage. The best reason to have one is the secure storage it provides. Drove F-150 S Cab's (2), for 15 years both with a shell. Unless you are going go the fiver route no reason not to have one. If you decide to add a wind deflector, and yes they work, having the shell enables you to mount it closer to the TT which dramatically improves its performance. We got an additional 1.5 to 2 mpg averaging 12.5 at 60. :C
