You said nothing on your touring experience, but one option you might consider is instead of doing your own tour, signing up to ride with ACA. A friend of mine did the Pacific Coast from Canada to Mexico with ACA. They had a van supported trip, so you only have to bring your lunch and water and rain gear on the bike, they haul your luggage and camping gear in the trailer.
Adventure Cycling does not list any trips on their website at this time, but once a vaccine becomes available, I would expect that they would start running trips again.

The upside is that they take care of the logistics and haul the gear. The down side is that every day is planned, so you give up the freedom to travel at your own pace. And of course there is a cost.
