Duet display is great.
Depending on our location setup, we typically carry an iMac 27" or 20", either shipped in the box from a friend’s house or sitting in Earthclassmail, or carried overland in a purpose built iMac case bag from the fabulous UK provider Flight Cases .com.
I have another 22" wide monitor stuffed amongst clothes in one of our suitcases.
When I dont need to use them, I ship them back to Earthclassmail (expensive, so I use it short term), or to my other storage warehouse at Ship2Storage in Murrieta CA (approx $8 per 25 cubic feet of storage per month or a large suitcase). Then summon whatever gear I need. I have my own DHL, Fedex and UPS accounts associated with my online retail accounts, so if I need to ship them further, and if my freight is cheaper than ECM or S2S, I’ll generate my own waybills and have them send it that way.
I tend to keep my carryons limited to the one personal effect and anything you can store in the plane, and shipping mostly everything else. I loathe boarding/deplaning, and when traveling with multiple companions it gets wormy quick.
We also travel with 3-4 iPad Pros and 1-2 PCs/Macs/Surfaces, which all stuff down quite nicely into a carryon. Duet can daisy chain them all, and I’m usually seen in airport or hotel lobbies with my noise cancelling headset and 3 screens in front of me.
So… you’re not weird. You’re just productive.
