We've found there is more interior storage. Exterior storage is different than the 2350. The rear storage is the same. We have added shelving back there-it's where we keep propane cylinders, beach umbrella, outside carpet and general cleaning supplies for the exterior.
We've lost depth in the side storage. We would keep our recliners there in the 2350; can't do it in the 2551. We redid the storage under the diver's side bed to accomodate the zero gravity recliners and our satellite dome for our Winegard Carryout.
There is another storage area, outside, under the kitchen area. We haven't addressed that yet.
