Make new options available for old vehicles

There are a lot of truck designs emerging that have built-in storage compartments in the bed, but maintain essentially the same basic dimensions as a traditional bed. Why not Ford offer instead of a new model generation that has a list of new features to attract buyers, you make new componentns available for upgrading older vehicles?

I just paid off my 2004 F150 that I bought used at 70,000 miles in 2007. I really have no desire to get a new F150 and return to making car payments every month. So it would be great to buy from Ford an OEM quality truck bed that has a bunch of built-in storage compartments, or some cool design feature on the new F150, for my truck that I want to keep for many years.
