Actually,it doesn't have cruise now,but I was going to install one if I come by a donor truck.
I don't like the wiper switch on 73-91 trucks.I guess I'm used to use lever on steering column,so it's kinda annoying to try find switch on the dash in dark.Even if it has light on it.And it's even harder to use if I have gloves.
On my '89 K1500,first it was difficult to use wipers because one lever had cruise and hi/lo+t/s,but after a while it was really easy.I even had remote for stereo right next to it,and that remote had lots of knobs.Hard to use first,but when learned,I didn't need to look at it when I changed the song etc.,just grabbed the knob.
My whole point is safety.If can get all the important controls close to steering wheel,I can watch the road all the time,but still use controls safely.I'm even going to modify my stereo remote on steering wheel/forums/images/icons/cool.gif.
