TJ......I apologize for the late response (I'm finally catching up on my back issues of FRF......)
DW and I purchased a gently used 2019 Isata 3 - 24FW with the booth dinette configuration (similar to the front half of your 28SS). I would have preferred the theater seats, but obviously purchasing used, it wasn't an option at the time. Our first trip was 10 days, and after about the 3rd day, we realized the dinette wasn't going to work for us....sure, it's fine for 2 people to sit and have a meal, but as far as trying to kick back and relax, and watch the TV......no bueno! The wife and I were never able to get comfortable for any period of time longer than about 10 minutes. We got home from that 1st expedition, and I ordered a power loveseat/recliner from Shop4Seats.com.....3 weeks later, I did the install myself (very easy, loveseat came in 3 separate sections). Long story short, best move we've ever made! We can now relax, extremely comfortable.....and don't miss the table or under-seat storage for even a second! The loveseat came with 2 side tables, but other than setting them up once when we first installed the recliners, we haven't touched them once. I had a folding table from Camping World
https://www.campingworld.com/outdoor...ck&cgid=tables .....works perfectly for the 2 of us for our 'fancy eating table'.....and stores conveniently between the loveseat and slide sidewall when not in use! Again, absolutely no regrets with the new theater seating (plus I was able to sell the dinette booth/table on Craigslist to help offset *a little* of the cost of the recliners!!!)
