Tonneau gas milage.

I'm considering getting a tonneau for my CCSB and most of them have se sort of mpg claim. I'm pretty sure this is bunk but anyone notice a difference?

Unless you have the 5.4 or the V10 I hope mean fuel mileage. Lmfao. Just bustin balls.

I had one on my S-10 in high school and it actually gave me 1-3 mpg better.

Hope this helps

While I don't have a 6.7 I saw very little if any difference with a tonneau on my 6.4. Personally I have been thinking of taking it off so I can put a tool box on. I got it because I like the clean look.

Please collect and message me Shell, Rotella oil cap codes aka "my miles matter" I'm trying to save up for a hat or something.

I have the BAK Roll-X on my truck and noticed no difference at all with fuel mileage however I like the Roll-X cover extremely well.

When it's not in the shop, I'm getting 20 highway and 14-15 around town. That's with 70-80 psi in the tires, nothing in the bed, nothing in tow, and easy on the gas. Under 65. I have an ARB hard cover on a short bed F350 Crew, 2011. But it currently has a blown engine. Yes, that's right.

I actually tracked this on my 6.4L I noted a .8 mpg increase with the cover closed. Did not test with open. Did not bother checking the 6.7L

I have not really noticed to much a fuel mileage difference, but it really nice to lock my golf clubs in the bed without worrying about them being stolen. I also bought a tool box that will fit under the cover so i can have the best of both worlds.
