Latest mod: Heated seats.
With winter coming soon I figured I would add some heated seats. I bought a kit on Amazon for $189 shipped. I did the passenger side first and it took about an hour and a half to get the seats torn apart, heaters installed, and seats back together. The seat bottom comes out fairly easy then you have to remove most of the cover from the pad by clipping the hog rings. I did have to buy hog ring pliers and a box of new hog rings which I found at my local Atwoods. The cover on the seat back is held in with velcro so it's much easier. The seat bottom needs to have a hole cut in the center and two notches on the sides for the hog rings. The seat back needs about 1.5" trimmed off the top unless you want to clip the hog rings there for that little extra. I didn't feel that it was worth the trouble. The driver side only took about 30 minutes since I knew how everything came apart.
After driving around last night my wife had to switch from high to low because they were getting pretty toasty, which is good! The only downside vs. the factory heated seats is that you have to remember to turn them off. They're wired to a switched source so they won't be on when the truck is off, so it shouldn't be a big deal. I did a quick chop to show the general heating area. You can see where it's trimmed on the seat back to follow the mounting rods on the seat cover.
