All you need is a travel dongle with hdmi displayport some USB-A and ethernet (If you really need that, tho) for me laptop screen on the go is good enough, have no usb-A devices (and those who have are upgraded to C using permanent usb legacy adapter mounted on the cable) and on the go, wifi/hotspot is good enough.

At home, ethernet and USB A are connected through the usb C 4k monitor.
