Just bought my PIAA 2000 series lights for the rear bumper. Can't wait to get home and get them and install them. I looked and looked for lights that would fit but the thing is made for the PIAA's Such is life. I am trying to decide which lights to get for the front bumper. Going to go with a set of fog and a set of driving to begin with. My coworker is going to give me a few 6" or 8" offroad lights. They are old school haven't seen them yet don't know who made them but they are free. Can't hurt to try them on the truck and see how they look.
You shouldn't have any vibrations at highway speeds. There is a chance of true death wobble, but is pretty rare. There are several companies who sell 3" lift springs for these trucks and even at that height most don't have problems. It can easily be fixed by removing the spacer or getting an adjustable track bar
I would recommend replacing the shocks with longer ones if you decide to do it
Just for a rough idea
I wanted my switches to look clean and I wanted them close so I didn't have to lean or move from the drivers position to turn them on or off. This is what I came up with.
This one was easy quick hole and done
This one however was a pain. Once the Cig lighter was yanked out I found a dash clip behind that was preventing me from having the left most switch on the panel. Lets just say with a little bit of anger everything worked out.
