2016 production could continue for a couple of months following the close of orders, so if you are asking in order to place an order for a 2016, then the date to know is when Ford stops taking orders for them, not when Ford stops building them. I'm going to wager a wild guess the order banks might close as early as Feb/Mar 2016, but more reliable information will come from a fleet sales manager at dealer.
Like the F150 transition from the '09-'14 body style to the '15-up body style, where some bed/cab/engine configurations were not orderable sooner than others, there could be some configurations of the 2016 Super Duty that get shut down prior to February 2016. For example, already one cannot order a 2016 F-450/550 chassis cab with a 6.8L V10 engine anymore, as the cut off date for that configuration was October 2, 2015. I don't know the reason why, but if I had to guess, there might be a shortage of V10s, as this high fleet demand engine needs to be available for the new 2016 F-650/750, as well as the E-Series cutaway and RV chassis.

Tire pressures
Just got my DRW and was asking about adjusting the tire pressures (which isn't real easy on the rears) when adding the 5th wheel load. The factory recommended on the truck post is 65lbs rear and 75 lbs front. However I asked my tire manufacturer, BF Goodrich, about increasing for load and they responded:
"We can, however, let you know that your LT245/75R17(tire size) can hold 2,755 lbs at 65 psi, 3,020 lbs at 75 psi, and 3,195 lbs at 80 psi."
Just wanted any input the forum DRW folks have to offer. Do you increase all tire pressures when hualing and reduce once you're not? Thanks.

72,000+ now, 30K of that towing a toy hauler.
Based on tire wear over the years (new December 2010) I run 75 psi in the front and 60 psi on the rears. I use to run 70 in the front, but wear had me going back to 75.
I have weighed the truck and trailer several times and each time the front axle load had been within 80 pounds, with or without the trailer.
Front tires were replaced around 45K and look like they may need to be replaced next year.
Rears are still the originals and I will probably change before the heavy snows.
And of course, your mileage may vary.

I run 88 psi minimum all the way around, because the tire manufacturer recommends that the tire and wheel assembly be pulled off the truck and rolled into a safety cage if the inflation pressure falls below 80% of the maximum inflation pressure of the steel sidewall corded tires, which for the Load Range G tire is 110 psi. 88 is exactly 80% of 110.

Mine are definitely Load Range E

My F-350 DRW has Load range E.........Max pressure is 80 psi !!
18,000 lb 42ft 5th wheel to Alaska and back.........
75 psi front
65 psi rear
Empty:
70 psi front
50 psi rear
I use the load charts from the tire mfg and consult with BigO tires, my tire dealer.......Ware is checked often......looks good, and empty, the truck rides much nicer.
That's my 2 cents worth..........Have Fun....
P.S. This is my third truck that I have adjusted pressures IAW mfg charts.

Yes, sorry guys, my dually is a chassis cab (F-550), so the tires (19.5") have a heavier load rating and a higher pressure rating. Similar tires are in F-450 pickups of 2015+, and earlier F-450 pickups from 2008-2010.
The danger of allowing these tires to be underinflated is due to the steel corded sidewalls. When underinflated, the steel in the sidewall flexes back and forth too much (approximately 650 times a minute at 60 mph), which like bending a tin can back and forth too many times, fatigues the steel and causes it to separate. A rapid increase in pressure, such as when re inflated, can be the "final straw" that precipitates a catastrophic zipper failure that can cause injury or death to the person inflating the tire up close.
This is why one has to use an inflation cage when inflating a tire that has been deflated below a given percentage below it's rating. And, Ford recommends a clamp on inflator with a minimum 6 foot extension hose for routine inflation, even when the tire has been maintained above the minimum inflation pressure.
Load Range E tires have a wider margin of operational pressures, given that they do not have steel cords in the sidewalls, only on the tread belts. This was probably one of the reasons Ford dialed back to LRE tires in the 2011-2014 F-450 pickup. But the market wanted the big 19.5" tires, so Ford returned to them in 2015. The 19.5 tires are not a bed of roses however. There is a good argument for sticking with an F-350 dually if the rated capacity is enough for the intended load.
