2025 GMC 3500 AT4. There isn't much room anywhere else to put the outlet. You could go lower to the side of the console but it would stick out towards your leg. It isn't ideal being vertical but the cap will help keep things out.
I found space under one of the useless area. It was pretty easy, worst part was finding power. They don't put any terminals in the unused fuse spots. I found a terminal on the drivers side fuse panel, it's hot all the time which isn't great but it's what I found. I fused it for 10 amps but ran 10 Gauge wire so I can go up if needed.
