Wow, great job on the redo. I love the bar mount for the antenna. I am also going to run a second location antenna likely off the bumper, or find a way to ground the frame of the future roof rack and use it as a ground plane. As a thought, since you are considering running a drill through NMO through the roof, I made mine multipurpose. If you use this model of NMO base
NMOKHFUD - Larsen 0-6000 Mhz 3/4in Mount with 17ft RG58/U, No Connector - ShopWiscomm
you can use the little flat pin inside to connect your dual band antenna to, and if you ever switch to a different antenna location, you can just pull the little pin in the middle out and use higher frequency antennas. I had planned to either use it for a dedicated triple trunking scanner antenna, or an externally mounted GPS base antenna. All possible with the 0-6000Mhz base. The antenna cable itself also offers better shielding than some of the others. The NMOKHFUD is the standard issue on all cop cars.
Since you wondered about those pass through jacks, I looked up my order sheet and found them here.
Amazon.com: Switchcraft EHRJ45P5E EH Series RJ45 Cat 5e Unshielded Feed Through Connector: Electronics and if you just wanted the crimp on ends, I have some and you are welcome to them, I just have to find them in my "ginormous bin o wiring bits" in the shed. Pretty sure I have the 4 pin RJ22 connectors too.
When you get ready to drill that roof hole, not sure how much experience you have with that kind of thing, but there are about 100 youtube videos that show you the wrong way, or the more wrong way to make that happen. If there is a video showing the right way, I haven't seen it yet. I'd be happy to talk it over with you, or help. I am hesitant about posting instructions in case someone does it wrong and blames me for it. Maybe I will make a video of it sometime.
Are you considering going in on one of those Incognito winch mounts from WGW? I am pretty much just dying for them to get released. I want to at least try it and see what I think.
Oh and on your rear door...the lack of a inside release on that door is something I consider to be a real downfall of the design, especially once drawers are installed in the back and you cant get in to fix it if the motor fails. I am planning to use this
http://www.summitracing.com/parts/hfm-sverkd?seid=srese1&gclid=COvrsYGW2MoCFQ9afgodqxAE9Q to run from inside into the rear door as a backup release system. Cheap insurance (and I also want to let myself out when I sometimes sleep in there until I get my RTT).
Most of those Euro radios are easy to hack, but the FCC is pretty much dicks about operating a euro radio here, especially out of band. That said I run a President euro 10/11 meter rig, and it is a rock star. I have a ground or tree based antenna system I can string up if I run that in the woods. Though there are a lot of Yahoo's on the CB side making a mess of the band much of the time. Fun to play with though. Do you use much 10/11meter in SAR around here?
Hope you are having fun on the upgrades. I'm waiting on a few schedule updates from people and then I'll be able to try to plot something with you. Oh, and if you make it down to Portland, just say hi, I'm right near Emmanuel Hospital. ( I wrote a lot, I must not want to be doing more homework)
Fixed the link to the passthrough connector.
