Thanks for pointing out that the Anderson plug bypasses the charge controller, I missed that.
At this point, I think I am going to go ahead and run a dedicated line back to a good quality 12v outlet and locking male connector which will replace the existing connector on the DC power brick. This will allow me to still use the power brick and ArkPak in other vehicles as well.
I want this new dedicated line to the 12v socket to only power up when the key is on, so from searching around it looks like I'll need to tie a solenoid or relay of some sort to the ignition wire somehow. I'm pulling together a parts list and am hoping I can pick everything up at my local marine parts store (those in Seattle, do you have a favorite marine supplier?). Can someone take a look at my list and poke holes into it and/or my plan?
1. Good quality 10g or 12g wire
2. Either a Fuse block (for adding other accessories down the road) or inline fuse (for now, add a fuse block later if needed)
3. Some time of solenoid or relay. I need some assistance here, would a solenoid be better suited or would a relay be enough?
4. A good quality locking 12v socket and plug like this

Am I on the right track here or am I over thinking it?
Thanks in advance!
