Finally got it done! Drove around in 110 and didn't notice it was hot till I jumped out. My son drove while I filmed. I have 3 sons and 2 of them want M923's now! One has a wife that looks at him like he's nuts but knows he'll do it eventually. My son driving doesn't have that chain of command to go thru, it's a matter of getting a place with a side entrance big enough or park at Dad's.I had to put it on medium fan as it started getting cold. I don't see a thermostat to control temp. I guess Red Dot figured in Afghanistan the HMMWV would get to cold with the sometimes 130 air temp. The side vents are perfect at deflecting the air to the passenger and driver as my son demonstrates. I turned it off for a minute to see the difference and it got hot quick. The next project is insulating the cab as on the drivers firewall it leaks heat like a 1500 watt heater is turned on! I am going to route the front vents or at the very least put louvers on them. The condensor fans go off and on and are pretty loud if you're outside. They don't seem to be designed to stay on all the time. Just sitting and not moving in 105 degrees they go on for 10 seconds then off for 40. I just picked up a twin M923A0 to this one with a soft top and will do an install on it. Have to make a different Evaporator mount as there isn't the back wall to mount to. I left enough extra hose on this install so when I relocate the batteries and put in 2 air ride seats I can drop the evap to the floor and make a radio tray or console on top of it. Well here's a few final pics. Oh yeah, I am going to offer AC installs with the M915 kits (I just picked up) locally at a very reasonable price start to finish on the M923A0/A1 trucks. Can do the A2 but cost goes up due to the Kenway higher pricing of brackets.
Here's a video of my son and I heading to the Burger King in cool comfort on a 107 degree day!

EVAPORATER IN THE CAB...Messy wiring and hoses need to be cleaned up. I routed the power lead from ignition and the compressor power under the cab to the front and the ign pwr lead thru the firewall back into the cab as I didn't want wires on the floor.

Compressor hookup and hoses (Kenway Eng brackets worked real well.

Fan control/filter boxes in the passenger side under the bed tool box. The condense is mounted on top of it. The hose runs under the cab from the compressor to the condenser, condenser to the dryer, dryer thru the cab wall to the inside evaporator. The only extra wiring off the harness was extending the dryer high pressure and fluid switch wiring plugs from the harness on the drivers side of the evaporator.

Extra hose left over. Also had a pile of fittings, extra O-rings, nuts, bolt etc.
