OBG, you are already a nomad.

With luck your EDC can always get you to your RV, which, as you say, you can use to bug-out or bug-in, or to your vehicle and its kit as an alternate for bugging out.

If the roads are not available or your vehicle is disabled, and bugging-in stops being a viable alternative, you are looking at a BOB situation. If your vehicle becomes disabled or blocked while you are bugging-out, then you are looking at a BOB situation.

Maybe add powered or unpowered cycles mounted on your vehicle, with BOB appropriate to cycles, to the repertoire?

And now you face a new "nomad v. base camp" choice.
