I wonder if the extra length would make the in-slide dinette as roomy as a non-slide dinette. Of course the above head cabinets would still be shorter; I'm talking more about the sit-ability of the dinette.
I understood that is one reason why the company stretched the 2350, to accommodate a larger slide out so a standard size dinette could be offered inside it. A dinette in the original smaller 2350 slide out, did not fare well with those who ordered it. There was no leg room and the table was much smaller. Now they'll have both along with a conversion bed long enough to accommodate someone like me at 5'-11".
If someone orders the 2450 with a dinette "NOT" in a slide out, they will gain a pantry along that wall.
I am curious to know if that extra space could be placed inside the bathroom, or to make the main closet larger with two doors instead of one, having top to bottom shelving in the right half. You'll gain a lot more storage with shelves integrated into the closet assembly, rather than a separate wall pantry assembly.
