When I retired in 1999 we bought a new pickup and a 21' TT. Our first outing was a 7000 mile round trip of the US. We saw the Pacific and the Atlantic and lots of interesting things that summer. We generally (and still do) stayed in one place for 3 or 4 days and explored the area in the truck.
Now, Pulling our little car gives us the freedom to go places we'd never go with the MH. Since we're travelers, not campers, the constant hook up and unhooking to visit places during our stay is not in our plan.
I like some others here traveled a large territory when I was employed and have a strong dislike for hotels and motels and only in an emergency would ever consider using one again.
What ever you do, take the time to see as much of every area you visit. There are many beautiful things to see in this great country. Oh yes, don't forget our neighbors to the North. Canada is absolutely beautiful!
Good luck ... Safe travels.
