We had the u dinette and sofa in our last trailer and were looking to get away from it. When looking at the table and chair setup, we found that in some brands, 2 of the legs on 2 of the chairs would be on the slide floor while the other 2 legs would be on the trailer floor, causing those 2 chairs to be off balance. You may want to check that on the unit you're considering. We ended up ordering our Sabre with the super lounge, which is a sofa that takes up that whole slide and has 2 tables you install on poles. It still has an airbed sofa. Might be something to consider, if it's offered. Our trailer was delivered to our dealer, and it's a nice setup, and makes the space a lot better when not eating/using the tables.
