If you could have only ONE improvement (besides the engine)

Only one thing huh?
Well...

I like everything about the truck as is.
But the 'Guage Cluster Dimmer/ Courtesy Light Switch', to adjust the brightness, needs to be changed from a wheel type switch to a push button on & off. Similar to the courtesy lights 'bypass switch' under the main veh lights switch, and the fog lamps switch.

well myself heres what i would like to see done
*better located window buttons (as ive said before)
l*ight in the back seat
*handle above the driver side of the roof
*and no attena sticking out of the car
*and instead of backseat that doesnt fold down all the way id have it so it fold down flat

Nothing that big that anyone can live without, but it would just make the car a tad more convineant/nicer
