We bought a 2013 3100rl and have the same question about the island. We have travelled with it between the recliners, between the dinette and the sofa and recently we moved the two dinette chairs and put it in the slide between the table and the wall. None of them make my DW feel comfortable while travelling, but have had no trouble in any of the places. One of the salesmen told us to put on the kitchen floor between the fridge and the fireplace and lock the wheels, that it would not move. Haven't gotten that brave yet. Afraid that it might fall into the fireplace. Wish that they would have made the island a few inches less wide so it would have been even with the kitchen counter to make it look like a full L-shape. I agree with Jim, the sofa slide should have been about 6" deeper and the sofa and recliner wouldn't touch. As Hook told me before we bought it, "It is a little Cozy". But we love the double fridge, 2nd a/c, king bed and of course the six point level-up. We replaced the heat registers with some nice oil rubbed bronze ones from Lowe's to make it look more elegant. We had the split bath in our last Monte, but we love the all-in-one that the 3100 has. We have looked at all of the models and haven't found the perfect one yet. All have something that we would change about them. It is a great little 5er though. We are fixing to change out the lights to LEDs. The size (35'9") and weight is a strong point also. My DW was worried about lack of storage, but after we loaded everything up, we still had empty cabinets. The looks can be deceptive. We have been pleased so far. Good luck with which ever you choose.
