So I've got the diamond plate installed. It's a touch short on the top, but not enough to complain about. Worst case, I have a bit extra and can machine off a section to put on the top when I get back from vacation:
It's wicked shiny if you're in the right position so I think it will do a good job of not heating up the bulk of the door when the door is in the direct morning sun.
Solar Steve suggested installing some insulation into the lock bodies:
Got the new probe installed from Ron at Store It Cold. Talk about wicked customer service! That guy is a rock star!
No door yet so it's not getting below 70 in there. I'm waiting for Ghettogyle Greg to help me lift the door into place. He's a freaking slacker lately.
So a couple hours later and the door is up:
Schitty pic but I ran out of light. I'll take a better pic in the morning. We still need to address a few little details around the door and grease the hinge pins (squeaking badly) but that can wait til after vacation.
Scottish and his lovely girlfriend popped by so they helped me wash the keg rack and put it in the cooler:
I'm leaving the cooler on overnight and I will report back on how low a temp it gets. I'm a bit worried as it's about to rain in a big way (thunderstorm coming in now) so it's not the best day to do a temperature test but it was at 45 F after putting the keg rack in there and the door had only been closed for about 15 minutes.
