Reading you post ... what is comfortable ... we have full-timed, traveled in a 28 ft. Alpenlite Travel Trailer for 12 years ... it has a separated rear bedroom and dinette/couch/kitchen in the other half. The only thing which we wished we had considered was needing a larger bathroom for two people. But we have customized the travel trailer for us these past 6 years and shall probably stay living/traveling/volunteering in it for as long as we are able to stay in an rv park/resort/campground ...
We chose this one at the time due to our other vehicle, now have upgraded to a 2500 Suburban and are happy with our set up. Will say that should we get another dog, as our now without a dog, would be a tight fit, but without a pet this size is fine for us. No recliner, but for now that is ok.
