Crazy Idea for my mid 70's AC!

[savatreatabvr]

I've got a 1973 Chevy c20 454 truck with the AC equipment removed, I've also got a wrecked 1977 Pace-Arrow Moho with a 110v roof top AC unit! I thought about mounting the 110v AC unit in the bed of the truck and piping the cold air inside some how but how do I convert the 110v to 12v? The 12v power inverters I've found that are powerful enough to run the 110v unit are very expensive and there's a 50/50 chance buying good used AC equipment from the junk yard so is there any other options?
