I think you meant 400.
Yep. At peak. Average power produced is probably around 200 while towing a large trailer. The Ford 3.0 is rated for 250hp so it could meet average requirements without much trouble. You would have another 350hp electric motor in reserve for accelerating and climbing hills. This motor would be able to reclaim a most of that power with regeneration in place of using brakes. Anyway, you would have 600hp on tap when needed, far more than most one ton trucks on the road. Even if you think that a larger diesel would be needed you should be able to see some benefit in never having to waste energy through braking. And judging from how a lot of people carry on about their engine brakes they must get used a lot. Also, as a side benefit studies have shown that hybrids rarely need their brakes serviced.

As far as electric vehicles, I calculate based on time to refill vs. range gained. Electrics still really suck at this. I'm absolutely sure I've ever said to myself, "Gee, right now seems like a really good time to hang out at the gas station for 30 minutes to an hour."

Ford just developed a new version of the torqueshift transmission for the F-250 6.2 for 2017. I doubt they are going to throw all that development $$ away and dump the 6.2 along with it 3 years down the road unless there is a major market shift or some other unforeseeable event. That kind of poor development $$ spend will get you fired quick like.
They develop transmissions for general power and torque ratings, not specific engines. I doubt that the new transmission will be discarded just because a new engine came out, especially one that was in development when the transmission was released.
The biggest threat to the new transmission is electric drive trains. I drove a Model 3 dual motor a few days ago and learned what power really is. Keep in mind that Tesla is using the same motor package in their new class 8's so don't say that they are not sturdy enough for a pickup. They do plan to use 4 in the class 8's but that still leaves them plenty sturdy for a pickup.

And I found this on the Electrical Engineering Magazine site:
"Battery scientists have a metric called maximum theoretical specific energy; you can read about the definition in Advanced Batteries by Robert Huggins. Right now, the most energy dense batteries you can buy are lithium ion, which are in the 100-200 Wh/kg range. I don't know what the best battery is, but later in the book, Huggins shows calculations that indicate that Li/CuCl2 cells have an MTSE of 1166.4 Wh/kg. (5x the capacity of current batteries!)"
So 5X what you get from a Lithium battery. This max battery may run at 1000 deg C tho...heh, or -200 C

Elon is building about 10,000 new charge stations per year charging at 480V and so far is using solar panels, not turbines to power them.

You may not know this but there isn't a lot of room for theoretical improvement in chemical batteries. Certainly not a doubling or more of capacity. And producing a battery with 60 times the current capacity would mean a battery 50 times or so the weight and volume. And would take a dedicated gas turbine generator to charge at 3000 volts....heh. And don't try the theory can be wrong line, chemistry is a very well understood science. Especially this sort of inorganic chemistry. Look at noble prizes in Chemistry most of them have been going to biologists or biochemists. There isn't much new being discovered in basic chemistry these days.
