Would be just like the other side with the ProPower. It can't be very deep because the tail lights are right there. From what we've seen tails appear to be identical shape on the 2024 trucks. I'm not against using that space, I have been a fan of the concept since RAM decided to make use of the normally wasted void. I just don't think that spot is going to be very useful on our trucks until we see some real examples of it on dealer lots.
I had Swing Cases in my 2012 F-150. I didn't want to cover up the Pro Power or the storage bin on the passenger side (even if it is small), so I found these steel boxes and bought 2 of them. This way you can move the boxes and set them up in different configuration. I got the boxes and foam pads, to protect the pro power when I put the boxes up against it. Both are from Amazon. Cost less than the Swing Cases also!
