If you got ice on the windshield it is best to warm up until the ice has cleared enough to see responsibly ahead and to the rear. The colder the harder wear is on the motor to run and get up to temps.

The difference in mpg right now i believe to be attributed to "winter" gas in much of the nation. Next late spring we will see much better numbers almost guaranteed. 🙃

You can easily google this question and come up with over 100 articles on why you no longer need to idle to warm up your car, here is a quote from one such article:
Idling in winter thus has no benefit to your (presumably modern) car. Auto experts today say that you should warm up the car no more than 30 seconds before you start driving in winter. "The engine will warm up faster being driven," the EPA and DOE explain. Indeed, it is better to turn your engine off and start it again than to leave it idling. (As many readers pointed out after this post was first published, it's always important to be careful driving in winter, and clear your windshield of any ice.)
So idling does nothing for your vehicle, but it does have several big (and avoidable) costs: Wasting fuel, and giving off greenhouse gas emissions and other types of pollution.

At least from your post it sounded like you were recommending that you should idle to warm up your truck prior to driving it.... if I read that wrong disregard this post.
Here is more info on why not to idle:
The Facts Behind Warming Up
It’s important to understand that “warming up” your vehicle in the morning doesn’t require idling. All modern vehicles were designed with cold weather in mind and can warm up just fine while in motion.
- Driving your car will allow all of the components to warm up faster than idling.
- Prolonged idling may damage the engine and its components due to incomplete fuel combustion.
- Prolonged idling may lead to the early failure of the catalytic converter due to its inefficient performance during idling.
- Idling contributes to the pollution more than driving as it releases more unburnt gasses.
- Warming up your car wastes gas and money, especially if your vehicle uses premium fuel.
- Idling your car inside a garage may cause dangerous fumes to enter your home.
- Leaving your car unattended while idling opens up an opportunity for theft.
Cars built in the last 20 years only need no more than 30 seconds of warm-up time, regardless of whether the engine runs on diesel or gasoline.

That is pretty old thinking, any car made in the last 20 years no longer needs to be warmed up before driving. Should you clear your windows of ice? Absolutely! That is what they make ice-scrappers for.

That's all fine when it's a bit chilly, but very cold weather like we get up here in Edmonton Canada requires more. The windshield needs to actually warm up to prevent it from frosting over again. Even my washer fluid rated for -50*C will still frost over when it evaporates if the windshield is still extremely cold and it's very dangerous and irresponsible to drive when you can't see and just hope that the vehicle will warm up quickly and clear the windshield. This is when accidents happen. Idle warming time is not black and white. It all depends on the temperature.
Be safe always, I use Anti-fog solution on my windshield so I never experience fogging of the interior front window.

Just bought a new 2.7l F 150, 3.31 locker rear end. Before purchase I drove all of the Ford varieties and the Dodge offerings including the diesel. They are all light years ahead of 10 year old trucks. Engine and rear end selection should be chosen based on how you intend to use your truck of course. I own a landscaping company and have a bunch of truck including diesel dump trucks. I wanted gas mileage and some light towing capability. If I have to haul something really heavy, I have other trucks.
All transmissions work very smooth, Dodge 8 speed and Ford 6 speed. All engines are entirely adequate for daily driving. Unless you tow something you will have to drive the Dodge diesel over 200,000 miles to break even on it. Diesel fuel and DEF fluid cost more, the engine/transmission is about $5,000 more. It is quiet and smooth and powerful....not particularly fast. The hemi is slower than the eco boost Fords and has variable displacement if I recall correctly. Those turbo engines are fast, surprisingly so. I passed a logging truck at one point on a two lane road. The 2.7 pulled very strong the entire passing time. I looked down and was doing 100 mph much to my surprise. I would like to know what the fuel shut off is on these trucks. My '06 5.4 might have been up to 75 mph in the same distance.
I purchased my 2.7 last Wednesday, loaded up and headed for the farm, 300 miles away. On the way back, loaded, I filled up, set the cruise control to 70 mph and the trip fuel gauge was reading 26.7 mpg when I arrived home. I now have 1,200 miles on the truck. That mileage is exactly twice what my 5.4 got on the same trip over the past 9 years. M1911

True. One thing I do truly love about the 2.7 is that when it's really cold, the grill shutters close to help the engine warm up faster and prevent the cold air from coming into the radiator and engine bay while driving. This definitely reduces engine warm up time while driving.
I assume you mean the speed limiter? I got mine up to 165KM/h (~103MPH) and the power cut out. Would not go any faster.

Did a 300+ mile trip back from Charlotte yesterday in the rain, averaging about 60mph carting about 2k pound trailer behind me. Averaged by the onboard calculations about 14.8-15mpg but averaged by my "this is how much I needed to put into the tank" calculations more like 13-13.5mpg.
Still not horrible considering it was windy as hell and I was dragging one of those big square uhaul completely not aerodynamic trailers behind me.
