As far as my "**********" goes, it stems from being in Ohio and watching perfectly good trucks laid to rest due to the salty roads! I just sold my f-150 heritage with an untimely case of cancer! I had planned on spraying the bottom of the truck with black bed liner.....but I couldn't stomach the idea of a mid 70's chevy two tone look. So my intention was to spray the grey part with color matched bedliner.
Since I sold that truck and the new Expedition is pretty well rust free (thanks to a life in Florida), I've decided to go ahead and mimic the two tone look of the heritage package. I plan on spray lining the bottom with a tintable liner that I can color match (the heritage charcoal grey). Any forums I've visited where someone even mentions this, and they instantly get flamed, but I love the look and it's VERY functional! Here is a link to what my intentions are...

Also, along with the host of usual upgrades (gotts mod, spring spacers, and TT).
I assure you once I do it i'll provide pics, for either your amusement or motivation!
