Here is a list of questions I had after looking at all the options on the Fords, along with the answers I found:
Stationary elevated idle control: These are standard on all models. But what is it? Here is a PDF file explaining it. It’s part of a PTO setup for commercial application. Not something I’ll need such as for a salt spreader.
Tire pressure monitoring: Depends how much it costs and if it handles the trailer at the same time. But then again it would be nice to have on truck when not towing. Trailer portion is an add on and handles up to 125 psi ratings. 110 pounds is H rated tires. Aftermarket cost for a pressurepro system for 4 tires is $392 and 10 tire system is around $500.
Trailer reverse guidance: Uses three cameras for backup coaching/steering guidance.
Upfitter switches. How are they used: Switches for stuff you add later such as flashers, lights, auxiliary fuel pump.
Active motion front seats: Seats that massage to help reduce lower back and leg fatigue.
Electronic locking rear differential. Non-limited-slip vs limited- slip axle vs Electronic-locking rear: Here is a forum post on the subject: “The e-locking 3.55 has a switch you pull out (the 4×4 switch) and it will lock the rear axles together creating positive traction (both rear wheels turn at the same speed). A non-limited slip rear axle means that only one wheel will be pulling at any given time and there will never be positive traction. Another option that is out there is called a limited slip, this is where during normal driving only one rear wheel will do the pulling but under a load there are clutches that lock up and cause both rear wheels to do the pulling.” Here is another forum post: “Limited slip allows both wheels on the same axle to turn even if one has no traction. Without limited slip, if one wheel is spinning freely in mud, ice, etc. then the other wheel won’t move. Essentially, a 4wd without limited slip or lockers on either axle is really only 2wd – one front and one rear. I strongly suggest getting some type of limited slip or locker functionality.” The electronic locking feature makes the truck handle it automatically.
Engine block heater: Here is an explanation of items you could add to a diesel truck for cold climates. Here is what Ford says: To ensure optimum cold weather starting performance, and improve cabin heating, the 120 volt engine block heater should be used during any cold weather operation. The engine block heater is required when the vehicle is to be started at temperatures below -10F (-23C). Here is a PDF for diesel care tips from Ford.
CNG/Propane gaseous engine prep package: This is a gas engine thing.
Engine idle shutdown: Some are programmable in 5,10,15 and 20 minute increments. May have something to do with California and “green state” emissions code. Shuts the engine off if it sits idling for a period of time.
Ford Telematics: Paid service for vehicle tracking, engine diagnostics, idle time, maintenance reports.
SOS Post-crash alert system: Automatically sounds the horn and activates the emergency flashers in the event of an air bag deployment or safety belt pre-tensioner activation. In addition, the vehicle doors automatically unlock after an air bag deployment or safety belt pre-tensioner activation, to aid in rescue.
High series cloth interior: Judging by the interior photos, this is the tighter woven material. I have it in my current Ford work vehicle (police package) and it’s good stuff.
Remote start system: It’s on the key fob. You can start the truck when not in it.
Tow technology bundle: Choosing the $ 1735 Tow Technology Bundle brings automatic high-beam headlights, rain-sensing wipers, adaptive steering, 360-degree camera and trailer reverse guidance, a camera in the CHMSL, lane-departure warning, and more.
Intelligent access (with push button start): No need to put key in the door. Just grab the handle as long as the key fob is within 3’ of the vehicle. It also has a push button starter inside.
10,000/9900 GVWR Package or 11,400 GVWR Package: The 9900 is the F250, the F350 single wheel can come in the 10,000 and 11,400 GVWR. The dually is 14,000 GVWR.
Alternator options: Dual alternators are standard with the diesel power stroke. (also comes with standard 2 batteries either way). One option is for extra heavy duty dual alternators. Some say it depends on what you are powering while towing such as a residential fridge. The extra heavy duty are a $115 option. Sent a message to someone that knows and here is the answer ” The dual alternator is certainly not (usually) needed. If you wanted to get a heavy duty one that wouldn’t be a bad idea but not really necessary for most RV applications. Here’s why:
- Unless you run additional heavy (like 2/0) cable to the trailer battery bank the charge rate through the 7 pin standard connector is only about 8 amps. That’s all the OEM wiring in the truck can take. Now, if you were planning on installing a true trailer battery charging system from the truck then naturally the dual alternator with much higher capacity would be needed and appropriate. Or if in the truck itself one needed a lot of 12 volt amps due to inverters in the truck, etc. But that’s not something most would undertake nor, in most situations, is it necessary. Solar is actually more functionally easier except in the most unusual circumstances where one would need to fully recharge a trailer battery bank during a day of travel after a large overnight depletion. I’ve built such systems for commercial situations and they are not an easy thing for most to undertake in most RVing situations. So the short version is: no. 🙂
Super (extended) Cab vs Crew Cab: Crew cab adds $4,685 while the 14” shorter super cab adds $2,860 compared to a regular cab. The shorter extended cab also adds 230 to the cargo capacity and 300 pounds towing capacity to the truck. Big decision as this will be our daily driver. The highest model that comes with a super cab is the Lariat and below.
What about skid plates that protect the underside of important things. They are about a $250 option?
