1. Get house ready to sell.
2. Sort stuff: toss, sell, donate. (you will keep very little).
3. Have one garage sale then donate the rest. I would not put anything in storage. If you have photos, digitize them or give them to the people in the photos.
4. Put house up for sale.
5. Decide on domicile state and set up mail forwarding. Change addresses on all accounts. Most banks have banking apps. Stop junk mail (I made a form letter for catalogs and magazines. Clip the address label from the publication, tape it to the bottom of the letter asking them to remove you from their mailing list, or cancel magazine subscriptions.
6. Get registration, tags and insurance changed to new mail forwarding address.
7. Make sure your health insurance is good in all states, many are not.
8. Go through your stuff one more time before you load it into the RV. If you haven't used it in 6 months, discard or donate. What do you really need. We do this every 6 months now that we full time. If we buy something we have to get rid of something.
9. Get appropriate America the Beautiful national park pass. Passport America, KOA, Good Sam and FMCA discount cards are what we use.
We also got the RV Plus Charge Card from Pilot and Good Sam. Or you can get the Pilot Flying J Rewards Card.
10. Get an RV GPS if you don't have one already. We use the CoPilot RV app.
11. Get storage items for the RV at big box or dollar store. Organizers, bins, storage containers.
Load stuff and take off and enjoy!! 7 years and counting!
