Well, having just made my first payment last week, I already got the itch to mess with a few things. "Stock" is such a nasty word anyway:). Nothing too exciting, but I'm pretty happy with everything and wanted to share.
First off, I bought some floomats/floorliners. The fronts are Weathertech brand, and the rear is made by Husky. Nobody makes a rear floormat for the 2-door Supercab, so I bought the cheaper Husky model for 4-doors and modified it to fit.
Fronts fit VERY nicely and are a very heavy duty, solid material.
Ford did change from a single floormat holder to two separate ones, so i did have to add two new holes...no big deal:
The rear fit great, after removing the side panels and trimming the mat to fit tightly underneath them.
Next, I added the 60/40 bench seat cupholder. Ford includes these on automatic trucks, but deletes them on manuals since they have the shifter console. The mounting holes are still present in the bench seat, so I ordered one from the dealer. The cupholder does interfere with the shift boot VERY slightly when slid all the way forward, you lose maybe 1.5" of travel. No biggie, and a place for cell phone/wallet/whatever is nice.
I do a lot of camping/fishing, so being able to see at night is always nice too. I replaced my solid red third brake light with an F250 cargo light, and wired it into the dome light. I also replaced the dome light with an LED panel, and replaced the cargo light/third brake light incandescents with LED bulbs. Conversion to LED was really only done in order to drain the battery less quickly when used for extended periods of time, and to hopefully avoid ever having to remove the cargo light housing again. So far it's been handy being able to turn them on with the remote unlock button.
Dome Light (basically the sun):
My last and most favorite addition were LED strip lights I added to the sides of the bed. I pulled constant 12v back to the Driver's side taillight, and wired the lights up to a waterproof pushbutton switch. The switch illuminates when lit, and it's mounted in an existing hole in the bed, up high where it should be fairly well protected. I really like the way it turned out, and they should light the bed especially well when I add a tonneau cover in the future.
I also got my bed Line-X'd a couple weeks back, I guess you can see that in the pictures anyway.
I took a lot of pictures while installing the bed lights, so I may put together a how-to eventually. Thanks for looking!
