Bed cap and fuel mileage

[Powder Extreme]

Those of you with the high style and roofline height style bed caps: I'm wondering how it affected your fuel economy. I'm wanting to buy an A. R. E. but am concerned about mileage.

Anyone know of a good dealer in Montana for the A. R. E. ?

I've got a roofline height cap, but I can't tell you if it affected mpg. I installed mine the day I bought the truck, from my last truck.

There is a site that shows the drag of different arrangements, on a pickup, but I can't remember if I heard about it from this forum or the Ford forum. I'll look around and see if I can find it.

I have a cab-high camper on my truck, (it was there when I bought it. ) I get about the same mileage as the other 12V/Auto/RegCabs I read about on this forum, 20-22mpg. Doesn't seem to add any mileage, but doesn't take any away either. Maybe the added weight offsets any aero effects? One thing it DEFINITELY does: it smoothes out the ride! I rode in another 2500 the other day, and mine feels cushy by comparison.

Here is the link to the thread that addressed this issue before.

Here is the link to the study that shows the drag information on various pick-up configurations.

On my dad's (now my sisters) '85 Toyota 4WD the shell was worth 1. 5 - 2 mpg. The shell is a cab hi snugtop.
