here's some of the mods that i would recommend to you
first since there's no real cargo light in back i went to wally world got some $20 lights and installed them as such:
switch
i'd recommend getting some backup lights installed these again are $20 from wally world. i have used these things more than i really care to admit, they're great for not only backing up and missing that big tree, but they also work well as work lights.
Another thing i have done and am very happy with is making my own center console. I had the factory rear heat, and it didn't really work. so i pulled the factory console out and built this:
I have my radio, CB, window switch, and misc other things all wired in there. and it works great! I used a 40mm can.
For extended trips it's nice not to hear all the road noise. So i used eDead and went through the doors, rear fenders, and from the front seats forward. Pretty easy to do just takes time. Clean the area well, cut and stick.
Another thing thats on my short list is to build a rear bumper with tire carrier. getting that spare out of the back, makes a huge difference!
thats a good starter list for ya!
