Now is the time to re-title a bus as a motorhome in Oregon. All offices are appointment only, but they are not accepting appointments for titling and registration.
I called the OR DMV (45 minutes of terrible hold music) and they said the inspection is not necessary, just pay my fees and send some forms in the mail. They asked me if the bus has sleeping and cooking facilities permanently installed I said "yes" and said they will take my word on it.
Insurance was easy too. Called USAA and told them I would like to insure my International S1800 "Truck" that is in the process of being converted to a motorhome and they said ok $30/ month for liability.
This took me a total of 1 hour.
