I do not have a cover but was wondering the same thing, if it would improve a little. Logically it should. I do not remember mine being worse in the beginning though. It just seems to have always gotten this. I do not tend to go over 70-73 max though on the highway. Every truck is a little different but I would expect you to be doing a little better. Btw. I have 24000 mi on it and so far it's been rock solid. No issues. I love it. Sent from my SM-N975U using Tapatalk

My 19 AT4, 6.2 with the factory lift and factory tires gets 16-18 in mixed driving and 18-21 on the highway. I was surprised how good it is. My 17 Ford 5 L never got higher then 16-17. I do wish I had my 34. Gal tank from the Ford in this Truck though.

I have a loaded AT4 in black with power fold, cameras, etc. in black and was thinking about the tow mirrors. Where do you live? I’m in north Texas.

I have had my 2019 AT4 since last May and have 20,500 mi and the only issue I have had is the brake pad monitor issue. Otherwise solid build thus far. Love the truck.

I have an At4 6.2 2019 with the factory 2" lift and get 17-18 on the highway at 70. I got 11-12 when I was hauling my 3600 lb airstream. I bet, like others have said above, that is not accurate. Sent from my SM-N975U using Tapatalk

Looks awesome. Maybe some black carbon fiber lettering for the GMC? I have it on my black one but think it would look great on yours as well. Sent from my SM-N975U using Tapatalk

I bought the same one you did, and yes it is a little snug. But it works. Sent from my SM-N975U using Tapatalk

What tounnea cover is that? Looks like one I am trying to decide upon. Sent from my SM-N975U using Tapatalk

Well that makes sense. Thank you. Btw the dark gray really does look great.

Okay first of all that looks really really good, so no disrespect in my question at all, but why not just buy a darker gray colored one to begin with?

Interesting. The seats in my f150 were definitely softer and wider the my AT4. I had a 2017 Lariet. I haven't taken a long trip yet though in my AT4 and I know sometimes a harder seat is more supportive and may be more comfortable on a long trip. Sent from my SM-N950U using Tapatalk

There is about 2 gallons left in my 24 gallon tank when it says "low" instead of giving a number. So at about 16-17 mpg for my 6.2. That's 32+ miles which is not much. Don't push it. The only thing I liked better in my 2017 F150 was the 36 gal fuel tank. Well, the seats were a little more comfortable as well, but I wouldn't trade back. Sent from my SM-N950U using Tapatalk

You bought a truck to match your dog! And they both look great! Congrats. Sent from my SM-N950U using Tapatalk

Thank you. Black looks a lot better. I agree with you. Sent from my SM-N950U using Tapatalk

I did the same with my black AT4 with the carbon fiber ones. Much better I think. Sent from my SM-N950U using Tapatalk
