You have your dual batteries in here. The reason for this was to get the dual batteries out from under the port side seats. You have more storage there now. I can now fit a surfboard and other stuff under there for storage and transport. My dealer mentions that they could transfer the batteries back under the port side seats for a couple hundred bucks in labor and some parts. So, it all depends what's more important to you. You gotta find a place for those batteries. I'm good with my setup as it is.
