What's the physically smallest router with good coverage and that can run asuswrt-merlin? I have an AC88U at home (soon to be replaced with an AX86U) which is still amazing, but very large. I'm looking for something that I can easily throw in a suitcase for family trips. It doesn't need to have any gaming features since it'll mostly be used for streaming video and will often be double-NATed on a spotty hotel connection. WiFi 6 would be nice but again, this is generally going to be backed by terrible hotel connections.
