Will be ordering a Lariat F350 SuperCab SRW 164".
Which package will give the heaviest front springs?
1. Snow plow prep (473)
2. Camper pkg (471
3. Snow plow/Camper pkg (47B)
4. Heavy-Service front suspension (67H)
I would think 67H would give the heaviest being that there is a note on the order guide saying that it will causing a rougher ride. I think I'm going to go with just 473. I currently have an '08 F350 that I plow with and the front end barely moves when I lift the plow. There is also a note in the order guide that only recommends the 67H option is you are running an aftermarket bumper or winch all the time, so for me I think that option would be overkill. I believe regarding the front springs, the camper package and the snow are pretty close. Maybe the snow is a little heavier in the front? Camper gives you the rear stabilizer bar. 47B gives you the best of both 473 & 471. I could be wrong, but that's what I'm assuming.
Figuring the needed front spring service would be much better if the packages did not contain "not included if maximum springs have been computer selected." Without the computer getting the correct selection for your needs is a crap shoot. When I purchased last week I observed the F-350's on the lot and some had 2 full length rear leaves and some had 3. All but one of the snow plow prep pkg vehicles had 3 and by the window sticker there was no other indication as to the reasoning of the difference. Even the sales manager failed to supply an answer. Since I am getting the camper package he was sure the heavier rears would be there to the point the dealership would make the capacity correct if not adequate. There is a guild for the campers, rv and towing and there must be a guide for the snowplow pkg. But even at the dealership it is almost voo-doo weight/spring calculations. That computer must be truly protected in the bowels of Louisville Truck Plant.
What is the difference between the Upfitter Interface Module (18A) and the Upfitter Switches (66S)? Is the module requires for the switches?
Somebody covered this already, but my understanding is the "module" is for use with equipment like emergency lighting and sirens, etc. The "switches" are what you want, they are the same as what you could always get in the Super Duty, except there are two more and they are located in the roof instead of the dash. I think that is really cool to have a row of aircraft-style switches overhead which light up at night!

Definitely not. The module is used to interpret engine and transmission parameters for use by external devices. It is part of the CAN (controller area network) system. For instance, with the addition of a bucket lift the module can control the power so that the transmission has to be in park and the parking brake set before the lift can be operated. Or that above a specified RPM the hydraulic take off pump will automatically disengage, or that a light and buzzer will flash if a preset speed limit is exceeded. I purchased the option by error thinking it was the upfitter switches, and then the saleslady did order the switches, thankfully.
For a F-350 SRW Diesel 4x4 crew cab 18" wheels the only axle ratio is 3.31? Maybe I'm not reading the chart on page 10 correctly but that seems to be rather limiting.

No, you can definitely get the 3.55 axle as well with 18" rims - 2nd row down in the axle chart. You will just have to order one of the packages listed in footnote 1. Most people get the snowplow package as it is very cheap (less than $100) and gives you the uprated alternator and slightly stiffer front springs.
What are some ideas that the Upfitter Switches could be used for? I know they are used by some for snow plows. And I've read of them being used for spot and accent lighting. My intended use for the F250 will be as a daily driver and for occasionally towing an Airstream trailer so I don't see me needing them. However, with six switches on the panel, Ford must believe there are a LOT of potential uses for these things. What do the switches actually DO? Is it simply a way to switch power on and off to an external device? Where do you connect the external device?
Pretending that I accidentally ordered these with my new truck, what possible (even far-fetched?) uses might be conjured up to put them to use?
Oops... should have started a new thread. Can't figure out how to delete and re-post...
I added them to my Platinum just for auxiliary external lighting.
By this do you mean accent lighting (for appearance) under the truck? Or do you mean that you use it to power lights that illuminate a work area (for example) near or around the truck?
On the diesels, most use them for the high-idle switch (my current truck I wired this way). If you had a roof-mounted strobe light for plowing, or say you were a call firefighter, these would be a nice factory switch turning those lights on and off.
Basically, they are pre-wired switches into the factory harness with relays and fuses already in place for super-clean installations. They are also of varying amperage's.
On my new truck, I will have utterly no use for them, since it is a gas. I ordered them because they look great, and do give you the option if some future use pops up.
The latter, I mean like some high powered LEDs on the rear to supplement the reverse lights and likely an over cab light bar or bars. I live on a farm way out in the middle of nowhere (like 30 mins to a gas station nowhere) and it get's dark out here. :-)
