The only thing of concern to me with the 2910 is the dinette in the slideout.
In the spring of 2007 when we visited the factory to make decisions on colors, fabrics, and options for our 2350, we walked through other models that were ready for delivery. One unit had a dinette in a slideout located on the passenger side. My wife and I sat in that dinette and thought it was very cramped to the point of being completely unacceptable. Our knees and legs were tangled up with eachother and the table was very small with no room between two plates across from eachother. I could slouch a little and hit the opposing bench seat with my knees.....I am 5'-11".
If that dinette was NOT in a slideout, it would have been just fine because it utilizes the extra wall space of the angled wall behind the passenger seat, and also picks up the extra wall space from the lack of slide-out walls. The distance between the two benches increases dramatically, and the table grows nicely. With the dinette setup as a bed, I can sleep on it fully extended, which came in handy when I got sick on one trip. Also consider that the floor is not raised and no walls tight around eliminates any claustrophobia, and the over-head cabinets become massive. It was an easy choice for us to get the dinette without a slideout for our 2350.
Just because a model shows a slideout in the floorplan, does not mean you don't have a choice. The factory would be happy to build that model without a dinette slideout. The money saved can be pocketed, or in our case, we spent that money on the full body paint job.
You decide what works for you. I am not trying to be a critic here with slideout dinettes. I am just passing on my take on the matter.
One final comment, on a personal level. Now that we have owned ours for about 5 years, I wished I asked them to add an insulated key'd outside access door to our front dinette bench seat. I place all my heavy mechanical stuff inside it to help in weight distribution given the fresh water tank is in the opposing corner. It would be so much nicer if I could get to my tool box, extra power cords, motor oil, jack etc. direct from the outside to avoid disturbing the interior.
