Figured I'd add some of my more worthwhile mods I've done. First is the reverse lights and conspicuity tape. The reverse lights are dually diffused lights from rigid industries and are super bright. Not only can you see whats behind you, but others know you're backing up also. There is already a hole in the body on each side so no drilling is required and the rhino tire carrier doesn't hit them when its opened. The conpicuity tape helps make the truck visible at night on dark roadways. With it being a flat color so it disappears into the night and a top speed of 55 I don't want to be run over by other motorists. Some trucks from the military already have this tape installed for the same reasons.
I also made my own brake light switch bracket and used the brake switch from an old jeep to make something much better than stock. When I switched to LED tail lights I couldnt get the stock switch to reliably function between the brake light never coming on or always being on, now they work perfectly. Part number for the switch is J5352620 and is about $12 so much cheaper to replace. I'm not sure if the switch could handle the draw from regular tail lights but it wouldn't be hard to make it activate a relay. I know the bracket is rough, its still in its testing phase
I also installed some overhead lights from thosemilitaryguys or something like that, they post in the classifieds here. It is really bright and the wiring is quality. I have one installed in the front and one in the rear on the cargo cover. You can also see the sun visors which are actually pretty decent when you need them.
The 4 man divider (not the 2 man which is longer) and radio rack come in handy with storage and keeping things where they belong. The rubber mat with holes came from Lowes and is really nice once your truck stops smelling like rubber. I thought of using stall mats but I like how these have holes so they wont trap any moisture underneath them if/when water gets in the cab. The high back seats are also pretty nice but expensive.
edit: adding something I just thought of. I had problems with water coming in through the small opening under the tail gate when it was raining. There is actually a piece of weatherstripping available that goes into that area and solves the issue, part number 12340780. I was going to fab something myself till I found out it already existed haha
