Dang man. Sorry to hear about the AC going on the blink.
It was 106 degree heat index the day we got there and the beach loop where we stay has no shade. The camper AC worked fine the first day and then the thermostat and control circuit board started short-cycling the compressor (off/on/off/on).
It was an older model AC unit (2006) with the old style slide thermostat and a new style digital with circuit board upgrade was actually cheaper (parts-wise) than a direct replacement.
I could've done it myself, but would have had to drive to Jacksonville to buy the parts, which would have cost more than what the repair guy let me have them for, and I didn't have all the tools needed either.
After weighing the costs for parts, travel, and a few tools, I really only lost about $125 above what my DIY cost would've been.
That's the cost of having a camper. September two years ago my b-i-l had to have his entire AC unit replace while we were all down there camping. It cost $1200 but his insurance covered $700 of it.
