Thanks for all the replies. Gave me a lot to chew on. Some progress has been made in just what we're after. And to answer PghBob, it will be used to travel the country, but not full time. Anywhere from week long fishing trips to our favorite SP to 2 or 3 weeks on the road sight seeing. About four or so trips a year (at this time).
The only plumbing we'd use would more than likely be the commode. At this point the shower is not needed, as would be the sink. But we have never had these features, so now we don't miss them. We are basically outside people, but in reality as we age more and more, inside comforts and conveniences may become desirable. A slide isn't "needed" if we find the interior space still comfortable without.
Looking at some model suggested we really lean towards the B+ because of the cab over and width. The cab over seems to disruptive while driving and see no sense of "getting used to it", if we don't like it, nor need it for storage.
Thor Gemini or Compass or the Phoenix Cruiser (both 23') would be possibilities if we can find an affordable one. Going to be looking for a while as we have more time than money. And aren't in a big hurry. Keep the suggestions coming.
Thanks all
