I present to y'all EXHIBIT A in my case for why we all need to have a good Mobile RV Tech and treat him or her like gold.
I was on a team Zoom call just now and grinding my teeth because Camping World parts desk hung up on me four times in a row (yes, there's a reason why we all hate them so much) when I heard my dogs going nuts and my wife talking to someone. She opened my door and yelled my name (even though the closed door means I'm on a call) and brought my tech into my home office with a grin on his face.

Thank you all for your help and suggestions. I've already ordered two replacement keys, but having this one in hand means I can access more crucial stuff like space heaters this weekend. Plus that's where I store my lug wrench and emergency triangles, which means I 100% would have had a blowout if that door was still locked (because that's how Murphy's Law works).
Anyway, find yourself a great tech nearby and treat him well enough that he won't mind doing you a rare favor. My wife gave him a great big hug, which lit up his face. "Forget COVID", he said, and than he gave me a big gorilla hug too (I guess I have whatever cooties my wife has, so why not).
Thanks again, everyone. Happy Thanksgiving. Go hug a tech!
