Ron, are you sure the slide out is different in the 2350 and 2552? I though the front portion was identical in these two models. The difference in the models being the bedroom and bath/the area back from the partition door.I understand the slide-out in the 2350 and 2551 is common to each other. The same applies for the 2351 and 2552 but is roughly one foot bigger. The extra foot is gained because the over-all rig is that much longer. That extra foot in the slide-out introduces a pantry with the couch and fridge. If you want a dinette in a 2351 or 2552 with a slide out, then you sacrifice the pantry to gain the space required as keelhauler had chosen above. I believe it is possible to get both a dinette and pantry along that wall, but only by eliminating the slide out. Eliminate the pantry too for an exceptionally large dinette.
Because the slide-out in the 2350 and 2551 is one foot smaller, the fridge with couch is your only option. If you must have a dinette in a 2350 or 2551, a slide-out is not possible for the dinette won't fit inside it.
Does that clear it up?
