I'd like to discuss preferences on which 12 volt power outlets (used to call them cigarette lighter outlets) owners think should be hot all the time (good to charge cell phone while engine is not running) and which should have their power go on and off with the ignition key (to turn GPS or other electronic accessory on and off with the key).
My truck currently has them all hot all the time, which I don't think is the best scheme. If Ford were going to change this setup, which would you like to be hot all the time and which should be switched?

Can we get some clarification on the axle selection on the F150? It appears that the 3.5L EcoBoost trucks get the 9.75" axle while all others get the 8.8" unless they're ordered with the HD payload package.
On the spec sheet there is a 9.75" HD axle listed, is this only for trucks with the HD package? What is different about the HD axle compared to the regular 9.75? Is it full floating? Can you share the maximum weight and torque input capacities for the various axles? The 8.8" axle has been reworked for the '15 F150, can you elaborate on the changes from the previous generation 8.8?

Also, can you go into some detail about towing capacities for each engine. The 2.7L EcoBoost is rated to pull substantially less weight than the old 5.4L V8 was in Max Tow trim. Is this because of power output and meeting J2807 requirements, or are there concerns about engine longevity under a higher duty cycle? Is there a weak link for heavy pulling, or is it all about power?
Lots of folks have reported lower fuel economy numbers under load with the 3.5L EcoBoost engine than the 5.0L V8 provides. Can you go into specifics on efficiency under load? Under high levels of boost are the EcoBoost engines less efficient than a larger N/A engine producting the same power?

Regarding the Super Duty chassis- if Ford can raise them with stiffer coil springs why does the general public need an adjustable track bar to do it right after adding a coil spring spacer? Does Ford have different length track bars depending on the different coils they install of the F250 and F350?

MPG display correction?
I have a 2015 F-150, and I find that the MPG display on the console is consistently about 5% off from what I calculate using the mileage/gas poured.
Is there a correction multiplier/constant that can be entered into the system to get it a bit more accurate?

Def gauge
Why doesn't ford use a display gauge for def level, also on the 15 model does the def have to be very low before refill vs refill anytime?

In case you didn't know, your roof design on both my old 2009 F150 crew and my new 2015 F250 allows a substantial amount of water to drop into the cab directly onto the switches that are there. Those aftermarket plastic rain deflectors you can add are still not enough.
The water from the roof of the 09 dropped right onto the window switches and the on the 2015, the water drops onto the mirror switches.
Just need a groove or a bead to direct it somewhere other than in the window. Knowing my luck it has been fixed on the 2016 versions.

My poor salt belt brothers and sisters need help.
What can Ford do to help us with the corrosion on
our Superduty's?
I have mine Krown sprayed, but it would be helpful
to see a design take our problem into consideration.
Thanks!

Lets talk real gauges.
Why can't we have cleaning exhaust filter left on like back in 2008.
Why no EGT guage when we all know one is needed and how about getting real gauges for the rest of the stuff so we don't have to go aftermarket?

I went to Krown a month after I got it ( April / 15 ) and asked if I could pay an extra $ 20 - $ 50 for an even better job. They of course said they do a great and complete job to begin with. ( this was at a bodyshop ) So I figured if I don't want it to go back there for anything other than Krown treatment I had better look into doing things myself. I have the
Fluid Film system in my garage now and have treated the truck with a few litres of the stuff in October....before the s-it hits the fan. I have the equipment to do a great job and have hit many spots and areas the Krown treatment does not do. Heck, I even let it run down the bottom of the windshield for where the water flows into the fender. Krown once a year and my treatment twice a year. I hope n pray but expect this to do me justice. My last truck was a 1996 Dodge 1500 and the FIRST sign of rust was two years ago. Then it went wild throughout the body. Fluid Film for the Ford !!! It will cost less than body repair over time and I like to keep my ride a long time and looking good.

This is a great idea for a sub-forum, and if the Ford Engineers are responsive, I can see it becoming very popular.
One question that seems to come up very often is the start-stop technology. Specifically, what changes have been made to the starter and the lubrication system to allow it to function without inducing undue wear? So far, whenever this topic comes up, it's all be conjecture.

Details on e-locker
Dear Ford Engineers,
I am the proud owner of a 2015 6.2l F-350 with the 3.73 rear electronically locking differential. I would like to know more about how the locking diff works. Specifically, is its action engaged / disengaged with a clutch pack or some other mechanism. What are the implications of allowing the diff to lock and unlock repeatedly, as might occur if one were to engage the locking feature while driving in town in the snow. As the vehicle speed crosses the 20 MPH threshold according to the manual, the differential will switch between open and locked. Is the diff designed for this sort of duty cycle or is that a safety feature that should not be used routinely?
I am familiar with the implications of a locked rear, so this question is specifically focused on the locking mechanism and its intended duty cycle / frequency of engagement.
Thanks for designing a great truck!
Best,
Dan
