RV Camper Big Buddy Changeover Propane Plumbing Install + Swapping Windows Remodel Computer Crash!

My Big Buddy by Mr. Heater is now integrated into my RV Camper main propane line along with the central furnace, stove/oven, and water heater. The main line now connects to a two tank changeover that works perfectly! Windows Swapping was literally meant in two ways. There are two main windows in my home that I want to swap with each other to permanently remodel the kitchen with the living room properly, and I think I've got a clever way to do it smarter instead of harder. Then, there's my computer crashing hard every now and then. As a coincidence, while I was recording this project I had to deal with the hard drive acting up again. I learn my lesson and back everything important up, getting spared a hard failure this time. A hard drive was on the way, and I guess another will be on the way again soon.
January 27 Update: I went to the mailbox this day after the last day it could possibly arrive still without the hard drive I payed for and ordered. Now, I will begin to figure out where it went and begin the extensive, often futile, battle for a refund or a resend.
