We have the 2720SL and love it. It was lightly used and came with everything on your list but 15” tires. It had the lift kit so 15” tires was one of the first modifications. I don’t know anything about the 2619 but ours is perfect for us. Small enough to store in the garage but big enough so two people don’t feel cramped and will comfortably accommodate 4 for socializing. We have spent 6 weeks in it a couple of times and rain or shine it just felt like home to us. We are planning a longer trip this fall so we will see how it feels to be in it for months.
Here is a post with a list of links to info on buying used. Some posts are better than others.
