As long as you choose them randomly. If you decide to use fd00::/64, or
something else predictable, you may run into conflicts ... but only if
you connect directly to their network. Better safe than sorry though.
The main reason I'm using v6 is that 2 networks I'm running a VPN
between both chose 192.168.1.0/24, and I can't change either ...

There are online random ULA generators - but I'm not convinced one of
them didn't give me the same block twice, or whether it was my own error.
