I think you can answer that if you wanted to. Look at any brand. Ford doesn't offer it. Chevy? Does ANY brand do it? No because they want you to buy a truck and they want you to buy the options because they make money on the trim levels and options. Ford loves the platinum truck sales just as much as FCA loves the limited. Chevy the High country because they are their money makers. Also it becomes very hard for warranty and support because they would have to update anything in the build reference of your truck to point to the upgrade.
Take a look at this from a magazine and this will tell you why RAM spent so much on the new RAM to make it so nice inside and luxurious. RAM Wants what ford has and is gaining everyday with 30% sales increase last quarter.
"Morgan Stanley analyst Adam Jonas has estimated that the F-Series, which includes F-150 and Super Duty trucks and remains the best-selling lineup in America, is responsible for 90% of the automaker’s global profits. Jonas recently said the F-150 alone
may be worth more than the whole company amid a slump in Ford shares."
90% !!!!! Thats insane. So if you want a fancy screen they rather you take the hit and buy a new truck than buy a part.
