State of residence for full timers

NEXUS - Passports - Enhanced Drivers license = Affected?

Just curious on the Mail forwarding/registrations etc, SD would be my choice, if there were any issues with the Govt - Homeland Security, on using them for Passport Residence?

I would guess in the way back when, it wouldn't, but nowadays??
Has anyone with the above had any problems in changing stuff over to the Mail service? or do they have requirements?

I live in a condo in Seattle, WA area, getting TC rig by end of year and will sell condo when market brings back the value to pay off VA loan. Once I get the camper rig, I'll be in it most if not all of the time cruising around.

So I was just wondering if anyone has had any issues with changing addresses with those items.

Thanks for any insight.. I don't really want to start messing around with them unless I have to.. NEXUS is great and I plan to hit Canada a lot.

Thanks..

(This might be a 'dead thread' but only alternative is to start a new one and seems like it would apply here too..)
