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.

most wind tunnel test I have seen show the truck only, not with anything behind it. Would love to see one with a tt behind it to see what really happens to the air flow.
