I run a Ram 2500 4 door long bed running 315's with a Snug and a rack around the Snug for my toys. I have a insert for the bed with cargo fitting to secure my stuff while driving. My rig looks like a contractors truck more than a overlanding rig. I live a bit closer to the bone than most, the RTT, Gazelle tent, slide out kitchen, Scottie are not for me, I camp as well as anybody, what I do works for me.
Eight foot drawers are a pain, they pull out forever, it's easier for me to hop up in the back to get what I want. I do like to sleep under the stars so I will use the tarp for my ground tent to do so. I don't like stuff hanging off the truck,
What are your goals and where do you plan to go, and what will do there? The size of the rig will limit some of the place you go. The rig just big and the distance between the tires is limiting factor, so is turning radius will also limit some trails. Good news, you GVW will not be much of a issue, You can camp large too.
