Between 1990 and 1991 my wife and me rode Harley's, she on a 1989 FLSTC and me on a 1988 FLSTC, to all 49 states, 3 Pra. and 2 Terr. in Canada. A trip that took 17 months none stop and was 87,000 miles long.
We camped, except for 10 days, in State Parks, KOA's, SAM's, and private campgrounds. During the 10 days, 1 day here, 2 days there, the weather was so bad we had to seek inside shelter.
The trip included the 4 corners of the States, the 4 corner States, And the principle cities in Alaska.
Two years later we flew to Hawaii rented motorcycles to get the 50 th. State.
Now that we are retired, we hope to do it again but now on trikes, she on a 2011 Harley XL883L, bumped up to a 1200 Race/Motor Trike and me on a 2013 Harley bumped to a Stage I 103 FLSTC/Motor Trike. However, we will be spending more time indoors because she will be 70 and me 71 in a few months.
