Proposed wiring for trailer

[JCDriller]

Hey guys, as usual I'm hoping I can bounce my trailers proposed wiring diagram off you guys before I start wiring it up. I think I've come up with a reasonable layout and I believe the wiring should be straight forward, but anytime I can get a second set of eyes I'm very thankful.

Please let me know what you think

Version 2.0, I didn't run the battery charger's negative leads through the shunt, this newer diagram accounts for that.
