This is by far the best mod I have made. Well, the @bambeds and my super-basic drawers might be tied for #1. Do you have bed drawers? - #48 by Ari
The only downside to the cable pulls is when the truck is full of nonsense camping stuff and I have to open the tailgate to get to the stuff in the back while trying to keep everything from falling out. However, this is like 1% of the truck usage time. Mostly its a fun stuff in the truck around the city, and the cable pull mod is great.
