So I wanted to include a few things that I really liked during my build. I didn't see many good references to things like this when I was doing my research so here goes, hopefully it helps someone out
Light switches
http://www.amazon.com/gp/product/B002UC13NEThese things are very nice, I have three individual light switches, each has a nice bezel and mounts about 3/4" deep with connectors on the switches.
Lights
Interior LED lights
http://www.amazon.com/gp/product/B00AQKC7LOOne of these lights up the Benroy very nicely, at least with the interior painted light colors (light blue and white). Has a switch on it, but I wanted to wire to main switch. I used two, one per side
Porch LED light
http://www.amazon.com/gp/product/B00EZY337EComes with clear and amber lens, uses an O ring around the mount to keep it water tight. Has a switch on it, but I wanted to wire to main switch so I could turn it on/off from inside. IE "is that a bear I hear outside?" click "yes, yes it is" click. Nice to not have to open the door to check things like that
12v and USB power adapter
http://www.amazon.com/gp/product/B003YJ8TVQNot as nice as I wanted, it has the standard car 12v adapter I cut off and wired up again. Works, but the 2.1a USB only gives 2.1 amps if you don't use the other USB port as well. Worked well though, has a dim blue LED that shines out so you know it has power. I wired this into my switch as well so I could turn it off to conserve power when not in use.
Exterior power hookup
http://www.amazon.com/gp/product/B009ANV81SI like this. Its cheap ($14) and has a nice rubber gasket. I installed this in my tongue box, and it has a short (8-12") 110 cord inside that you can plug a normal cord into (female end of ext cord). One of the cheaper ones I could find, but very happy with it.
Main Fuse
http://www.amazon.com/gp/product/B002IVEIBGPicked it up, and it was just long enough to use the cord as my hot terminal off the battery to the fuse box. Crimped on some ring terminals and I was all set to go.
Fuse box with negative bus
http://www.amazon.com/gp/product/B000THQ0CQ6 circuits, easy to install, easy to setup, no need for a separate negative bus! Ring type terminals connect positive and negative to the battery, and this will run my entire teardrop otherwise. Both lights on one side on a given circuit (fused 5a) each 12v and USB chargers on a separate circuit (fused 15a) ceiling fan on one circuit (fused 5a) and the galley power on the last one (fused 15a)
Battery Charger
http://www.amazon.com/gp/product/B002DU3S9ASeems to work well at least on the little group 24 battery I chose to use. This is currently the only 110 power in my camper.
Battery box
http://www.amazon.com/gp/product/B00EOX2QJCWhat can I say? Its a box, I put a battery in it. I bolted this to the frame directly with two bolts, fender washers, and lock nuts, but yeah otherwise, its a box.
