Do you have a "home base" or are you fulltimers? I have gigabit fiber to the house, so I use that to bounce all my traffic off my home, regardless of where we are. For that, I use Tailscale. It's super easy to set up and you can run a system on your home network to use as your "exit node." Basically, it ensures anything you do is encrypted from your device back to your home, then it goes out to the internet from there as if you were sitting on your home network.
It uses Wireguard instead of the outdated OpenVPN base. Much faster and more secure.
