So I have a lot to post about this. Hopefully some might find some of it useful. I also likely will have a few questions but honestly with the vast amount of info here on these forums I actually cannot really think of much as I actually know how to search on forums and read first. Crazy right.... 
Anyways I've already done of a ton of things but first part is what I have.
2003 803A with 20 hours - bought from a member of the local MVCC for considerably less than they go for on that auction site... He was kind enough to check it over, install two new batteries, and gave me a spare fuel filter, oil filter, and water separator. Handy to have those off the shelf part numbers.
It came on an 2010 Schutt LTT-HC 1-1/2 ton trailer. It is now mounted with the control panel at the rear. Manuals are still sealed and in the side box as well as a "Depreservation Guide". Did have the ground rod, ground wire, big plastic wrench still tied in, aux fuel hose.
Short list of mods so far in no particular order....
Future plans -
Going to have an expert welder buddy make a full custom aluminum belly tank for the trailer sitting above the axle and going up between the framing for greatly extended runtime. Hoping to get close to 125 gallons or more. We will pull the gen off, pull the axle, flip it over and figure it out. Should be fun. Part of that will also be including a fuel transfer pump to make filling out small tractor much easier and using it in that manner will also help to keep the fuel fresh as well as filling it up much easier (just tow it to the local station),
Getting some smaller stock plain steel GM wheels so I can put some smaller (and easier to replace) tires on it to lower it down to a somewhat more reasonable height for towing with a typical 4WD pickup. I have an H2 that is lifted with 37's - that does happen to tow it perfectly level but in the long run I do not plan on keeping the H2. Even if I put 31" tires on it, the lounge height is still going to be pretty high for the typical pickup but will at least be considerably better than it is now.
Anyways - pic of it behind my H2.... Hopefully most here know a bit about the H2. While far from an HMMWV the common public conception that it is a Suburban with a different body is far from reality as the H2 was built by AMG under contract right next to the H1. I can elaborate more if someone wants (the little H3 is however a just a Trailblazer with a different body).

Short list of mods so far in no particular order....
- Replaced both of the leaky fuel tank rubber well nuts with brass ones.
- Replaced the vast majority of the external rusting screws with new stainless ones. My God there are a LOT of them. Probably 10% of the originals broke off.
- Flipped the extremely faded fault indicator panel over and painted new graphics on the back side. (I posted a vector artwork PDF in the documents section if anyone wants to do that.
- Fuse mod had not been done. I did that, and went further and replaced the 400v diodes inside the VRM with 1000v ones for additional assurance that will never be an issue.
- Coated all of the faded paint with Penetrol to darken it back up and bring the color back.
- Added a switch to the control panel that is tied to the circuit breaker inside to make it more significant other friendly (she is not going to want to open the panel, just getting her to open the side to flips the dead crank switch is enough). Also added a military nuclear indicator light to come in with that switch for S&G.
- Grabbed a full Pulse Tech kit that has the 12v/24v circuit breaker box, solar panel, battery charge state push button box on eBay (auction and got it for $65 for the whole kit. I'll have to do a full reply later on how I utilized that.
- Converted the trailer tail lights to 12v (all markers were led so already 12v ready) and replaced the 12 pin connector with a consumer 7 pin one.
- Replaced all of the fuel return line.
- Bought a correct style slide hammer for the ground rod since that was missing.
- Added aluminum screening to the side air intake vents and the bottom vent as we have a LOT of dirt daubers as well as field mice which love that sort of thing. I did not do anything with the top vent yet - still debating on that one. Thinking on just making a flip up cover for it that can flip over the back end when in use but on top to keep leaves, etc out when not in use.
- Picked up an M60 AP distribution box with the 100' main big cable and one of the shorter 50' smaller cables for the cables and parts I wanted. Mounted the female from the box to the gen wiring output hole, male to my breaker panel to a 60A breaker and added an interlock kit. There are some gotchas I discovered with that bit of kit I'll get into later...
