Thanks for all the information and tips everyone!
In the end I’m gonna end up doing a combination of things.

Spinning disk drives and power supplies are removed from all systems, large unsecured cards removed from desktop so they can’t flop around on the PCIe connection, servers removed from rack, everything wrapped and strapped down as needed.
Drawers mounted in the rack will also be removed as well as UPS, everything else weighs next to nothing and can be safely left in the rack. Most likely store stuff in the cavity of the rack and then wrap the whole rack tight in a plastic packing wrap. I’ll get a moisture control box for closets, bathrooms, mud rooms and storage stuff to help control the humidity inside the trailer during the move.
My trip will end up being around 1,600 miles in 2 parts. From Texas to Iowa to Virginia, so who knows what all kind of weather I’ll be hitting.

Thanks again for all the help, I’m pretty confident I’ll be able to get everything moved safely.

I like the plywood and felt pads idea, thank you.
I’ll definitely be taking all the hard drives out and wrapping and packing them in boxes.

Probably be Ente even if it does take a little bit to configure it and get a web UI and stuff. PhotoPrism was easy for me to get up and running with Proxmox and the great community scripts to setup a container but having to have photosync is a drawback I don’t care much for.

I believe both have something to like a memories feature

I’ve been using Ente Photos, and PhotoPrism and I’ve been liking Ente pretty well. Little bit more work to get things setup and going but I’ve been enjoying it for the last few months

I’m not much for watches and stuff. I have my phone, it does what I need and then some. But that is one nice looking watch.

Simple but elegant.
