Though we've given up our Airstream and returned to a Class A (for spacious interior living area and storage), I thought I should show what the recliners did for our 2016 30' International Serenity. The recliners did make the Serenity about as comfortable to hang out in as it could possibly be!
We removed one of the two dinette benches to make more floorspace for our two pups to relax.
We typically sat in our recliners and only used one of the dinette benches, on occasion, individually. We did find the dinette top exceptionally valuable as a working space for a variety of functions including load in, cooking, beverage bar etc.
Much as we appreciated what this Airstream offered, we found the interior floor space just too confining for us (two of us with two dogs) and the storage was no where near enough for us. When RVing, we tend to spend a lot of time hanging out inside the RV. That's why we're now in the Newmar 3124 Class A. Aside from that, the Airstream was an awesome RV!
