Next was probably my biggest mod: heated leather seats. Owning a dairy farm, I'm usually covered in something and the stock cloth seats are basically huge sponges for all of it. My dad has asthma which got a bit worse when he got his 05 with cloth seats so we decided to do both of our pickups at the same time.
We bought leather kits from canadaseatskins.com. Mine was a Katzkin base level kit that I ordered with dark insert and light outer as well as contrast stitching. That came to $750 ($50 off for ordering 2 kits at the same time). Then I bought a set of seat heaters off of ebay for $80. Then came the fun part, install. It took me 2 nights of about 6 hours total to take the seats out, take the cloth off, put the leather on and put the seats back in. The jump seat lid was by far the hardest to do and took the most time. The seat heaters are fairly straight forward, just apply to the bottom and back of each seat, plug the harnesses together and hook up the power and ground. The Katzkin leather is a great kit with a great price and help keep the air in my pickup alot cleaner
