Because then they would not be able to advertise their worthless snow plow button of added complexities. Also people are suckers and fall for that gadget crap. Plus Ford can still continue to use their bare minimum wire sizes, cheap smaller CCA battery and smaller cheap alternators on their $30k+ truck.

 

I suspect Ford uses the proper wire size for a given job (you know, engineering and all), a sufficient battery to crank the truck in the circumstances where it's needed, and their alternator is sufficiently large to keep up with the truck's maximum electrical demand (while having an active management system that will reduce its output when not required).

Oversized wire = additional weight.
Oversized battery = additional weight.
Oversized alternator = additional weight + additional inefficiency.

Wanna guess what 0.1MPG on their CAFE rating costs Ford? Plenty to make it worth shaving off every ounce of unnecessary weight.

By the way, I've done several emergency equipment installs into F150s. My personal truck can pull 80-100A continuous with everything running, all lights running, both sirens engaged, etc. Never had an issue with the alternator not keeping up.

 

Slurp, slurp. Mmm that kool aid is good.

Yeah ok.

 

Well, you may doubt me, but my amp clamp doesn't lie. Keep in mind, this includes 2 200-watt sirens, wig wag headlights, about 30 lightheads, a 30" console full of radios, computer, and a few other toys.

 

Here's a nice group of videos on BOSS plows. BOSS SNOWPLOW - YouTube

Ford and BOSS developed this plow to meet the needs / capabilities of the 2015 F-150. Mount anything other than a BOSS plow to your truck and see how fast Ford turns their back on you when you break something.

I see landscapers down here all the time mounting heavy plows to 3/4 ton GM's and Fords and these contractors clearly have no clue what in the hell they are doing. In many cases, the plows are much bigger and heavier than what is needed to get the job done. The trucks look they are doing a nose dive into the pavement. That only serves to wear out all kinds of things prematurely.

So, the naysayers can say what they want. This is not a commercial application but rather for home use. The truck and plow application are rated for that use. If you want to remove snow from a Walmart parking lot then buy the correct equipment.
