Thanks everybody for the comments!
Things went fairly well.
I initially ignored the part about what socket to have for the water heater anode, thinking I could probably use some other wrench to accomplish the same goal. NOT. No real harm done though, as I realized it pretty quick and had to make an extra run to the store to get the right tool.
Also, it turns out that my trailer isn't pre-plumbed to make this super easy. There's one hose from the fresh water tank to the fresh water pump, but no valves or spur hoses to direct suction from an anti-freeze jug rather than the tank. No big issue though, since pulling the one hose from the pump inlet and adding my own stub hose was easy.
One other thing I saw in a different video than the one I posted had to do with the shore water connection point. At the very end, after making sure that the water system is depressurized, it suggested pulling the screen from the shore water connection point, and pressing in on the check valve until no more water comes out. That drained a little water as well.
