Help me convert a box trailer into a mobile workspace

It's a 6x12 Loadrunner with double rear doors and a side door. The only thing installed already is a DeWalt Toughsystem rack with some boxes, and I will add another one of these soon. I carry around misc tools, wiring, connectors, electronic gear, etc, but I still have a good bit of space to work with. I'll need a workbench to do some repairs and quick projects out in the field.

I have access to any equipment required for modifications. I could build an entire trailer from scratch if I had to, so no issues here.

I have a lot of things in mind already, so I will go over those plans and then I was hoping you guys would think of things that I've overlooked or could tell me if some of my ideas are stupid, impractical, or just won't work.


Power
I hope to avoid a gas generator if I can, though I will probably haul a small one around as backup. I found these nice thin and flexible solar panels that I can glue to the curved roof. I haven't done all the calcs on how much power I will need, but I can easily fit 500+ watts of panels up there if I need to. Batteries, charge controller, inverter, etc, I think I'm good here.

Cooling
It gets really fricking hot in there, and while I think most everything that I will ever keep in it can handle the heat, I'd rather keep it below 90 degrees all the time and mid 70s when I'm working in there. I will install a few low power exhaust fans to take the edge off, paired with a DIY thermostat for automated control. I still have a lot more research to do on AC. I know there are plenty of 12v and 24v options for RVs, but most I see are way overboard for such a small space. Plus they're mostly roof/ceiling mount, and I may not have any available roof space. I was hoping to find a low voltage wall mount split unit that I can hang in the front and avoid cutting a big arse hole for a trashy looking window unit. I would love if I can automate it. I will turn it on manually while I'm working, but I would also like it to run on its own on the hottest days to keep it below 90 as I mentioned. I figure on these hot days my panels will be making power with nowhere to put it, so might as well burn it off to cool the interior and keep the batteries topped off too.

Lighting
I will be using a lot of rgb led strips inside and out, I'm a sucker for sweet light effects. I will make them smart to respond to events like doors opening and motion inside and out.

Workspace
Workbench with misc tool and part compartments. Might make it fold in/out. Outlets, lighting, other office type stuff. I'll probably just DIY the whole bench and modify as I go, doubtful I'll find anything to just bolt in.

Connectivity
I will outfit it with cellular, wifi, and ethernet with PoE. I'm also considering a PtP wireless radio in case I can set up a solid connection on occasion.

Security
With all the time and money going into this project, not to mention the value of any gear I might be hauling, I definitely want it to be secure. Cameras are a must, but due to power and data constraints I will try to be clever about it, likely with arduino cams. Since I will already have PIR sensors to activate the lighting, I will also have the cameras snap a couple of stills. I can also take some shots when the trailer itself moves. The photos will be stored redundantly inside the trailer, and it will only transmit them if it determines it has been stolen. It will of course track its location via GPS at all times, and report back via LoRa if available and fall back to cellular if not. The tracking gear will be hidden and have its own separate battery backup.




That's about all I've got for now. Have I missed anything, or is it already way too much? This project will probably drag out for quite a while, so if there's interest I will report back every now and then on the progress. I also hope to make some youtube videos about it all, and who knows maybe it'll turn into a side business modifying and selling trailers.
