Lift and larger tires go hand in hand. I got larger tires before my lift and had some rubbing issues. Sliders are also very high and early on the list. Not only for protection but for when you need to lift the truck up at weird angles.
Two things:
Rago Fabrication Modular Storage Panels
Raingler Nets
The storage panels mount where the back windows are and you can use it to hang up just about anything. Knives, shovels, axes, etc. Very easy DIY install.
Raingler nets makes stuff for storage as well as for dogs. Very cool...
