Thanks wanted 33. Yeah the start stop worked when I had the ac on earlier so it just depends on a lot of factors, I suppose. Not sure why everyone keeps saying the truck won't get "good" gas mileage. Do they not get the MPG the sticker says? What are you getting mpg wise?
They should get close to the rated mpgs. My previous '13 F-150 with the 5.0L was rated at 21 highway, and it would do that on a perfect day. One of the things to remember is the manufacturers methods, most of time, don't recreate the real world. We have to drive in rain, head, and cross winds. All of those kill the mpgs on the rolling billboards we call a truck. That old F-150 would lose 2-3 mpgs in ahead wind on the interstate. I'm a bit older than most here I suspect, and remember the day when I was happy my old truck would get 10 mpgs. Never did I think I would see a full size truck get even 21 mpg. And, they do it so much more comfortable than the ones of yesteryear.
One thing to remember, in town driving, and the way you start from a stop has the greatest affect on mpgs. I have a '20 Ranger with the 2.3L turbo now. First turbo I ever owned. I was getting crappy intown mileage (10-13 mpg) until I found I was putting my foot in the turbo everytime I pulled off from a stop. I learned, and it does 19-20 around town now. That big old right foot gets me into trouble a lot of times. And I'm betting my Ram with the 5.7L will suck down the gas until I get used to that beautiful music coming out of the tail pipes.
BTW, all this is from my past experience with trucks. My Ram is still on order. Hopefully I can put it to the test soon.
