Good info, thanks. I don't have access to a break right now, almost bought one, almost... We did some testing on 0.06 stock and the spoolgun. I set it up so the voltage was just below the spray transfer threshold, with high feed rates. If I move quick like you mention I get minimum bleed...
If you have the space, one of these slightly larger 8kBTU units would be an easier donor. Its already partially split, with separate evap and condenser fans/motors.

Counter is 0.25. Most of the body is 0.1. Drawer faces are 0.1, sides vary from 0.065 to 0.1 depending on bin size. I still have some material I can remove to save weight. Its a balancing act, removing too much material will make it prone to warping when I start welding. Though I probably...
I will try to find some photos in a bit. This method consists of making a light skeleton of 2x0.5" or similar square wood. This outlines the cabinet and gives it primary strength. Then a 1/8-3/16" strong plywood is glued/screwed over the frame. This forms the skin. The resulting cabinet is...
Here is my old galley. Note there is no back panel. I used high ply count 7/16-1/2" plywood. Joints are Kreg socket screws and glue. Some steel angle brackets as well. After 90k miles (about 10-15k of dirt, including australia), some of the smaller joints had started to separate a bit. I...
Typical home style cabinets from wood are a bad idea. Marine style frame and face, especially with plastic totes works. My cabinets are very light. I think my galley is like 35 lbs empty with sink and stove.
Rattles and whatnot of the cabinets themselves aren't an issue with proper fasteners and adhesives. Same goes for packing stuff into cabinets, if you use good containers and packing methods rattling can be kept to a minimum.
Wood works fine if you use proper joints, ideally with pins and glue...
Got the battery box steel earlier this week. Came together okay, though I am regretting not getting a rental bottle with C25 shield gas.

Got the evap fan tested. I forgot to account for the foam seal pushing the fan housing down, so some adjustments were needed to stop rubbing.
Since I have a second fan motor, I need another 6UF starter capacitor. Also, with two motors I can now have the condenser fan turn off with the...
This is the shelf which goes over the rear doors. Just barely fits.

Adding line stubs to get outside the case.

I found some low loss quick disconnects which should allow me to remove the unit for service if required.
Doing some quick math with R32 at 160 BTU/lb and needing 5000/160 =31.25 lb/hr. I should be good with 3/8 body for liquid and 1/2" body for suction. I will need to top the charge every...
I welded on some quick-n-dirty brackets. 4 rivnuts into the floor supports should do the trick.
I did some measuring, and the evaporator will barely fit in my over-door shelf. I need to modify it a bit, but not a complete rework thankfully.
The next step is to figure out where/how to...
It just barely fits between the floor supports.
There is a nice scalloped area for the spare tire clearance. It should provide enough space for exit airflow.

As you can see, it hangs down a little bit below the hitch. Should be far enough forward that my departure angle won't be...
If you see the previous thread I linked in the OP, I ran this unit for a whole day (stuck through my front window) and monitored power consumption, noise, and performance.
I also think you might misunderstand what BTUs are. A BTU is a measure of energy (analogus to watt-hrs). Power is...
