I'll start with the caveat that I have not gone fulltime...yet. But my folks did for about fifteen years and then "most timed" for several more. They had everything at one time or another. TT, 5'er, Class C, Class A, and finally a Class B. When they went to the B it was not as full time but they would still stay out for many months at a time. I think it's a matter of what you need to have with you vs. what you want.
That being said, we are going to set out in a month on our first experiment at an extended trip. From WA hoping to be in FL by mid December. We decided on our 31 ft Allegro because it seemed to be a good size for us. We were originally looking at the View. I really liked it and think we could have been OK but the DW wanted a bit more room. The older I get the more I want small, simple, uncluttered, and uncomplicated....but that's just me.
