Cheryl, I only have a 22' rig. But it has a floor to ceiling storage in the kitchen, and another wider one in the bathroom. The bathroom also has a cabinet over the sink way bigger than what a medicine cabinet holds, and a big cabinet under my sink - for a tiny little bathroom, it's amazing. Most now are lucky to have a cabinet under the sink at all ... no other floor to ceiling, and some the medicine cabinet is so dinky as to almost not be worthwhile. My corner bed has the overhead storage including a shirt closet. You can still find those, but more often they just make the overhead longer - so without that floor to ceiling storage that is really supposed to be for the kitchen, you might not have any hanging space.
If you go to a 24' rig, it'll have my bedroom cabinets, often without the shirt closet. Only a medicine cabinet and maybe a dinky under sink cabinet - but some don't have that and put in fancy pedestal sinks instead. It won't have the floor to ceiling cabinet, in most cases. It will have a clothes closet and drawers. That MIGHT make up for part of the missing cabinets, but not all.
Many kitchens make the cabinet next to the microwave not as deep as the microwave. Mine is - so has extra depth.
If they give the cubic feet of storage, most 24-25 feet models inside storage is less than mine ... and that just infuriates me. Doesn't mean I won't end up with one of them ... but I know they can do better.
They claim it's because they give the larger outside storage. That can work for some ... and I would like a little bit more outside, but often that one big outside storage space is hard to use ... having to move things around ... unless you are lucky like Liz with a sil who organized it for her so well
My valves for my black and grey tanks are in a cabinet - so while my tanks aren't heated, they are enclosed. And in that cabinet I can fit some things -like some sewer connections, and an outside rug, and my orange leveling blocks. I have other outside storage, also - that gets other things - instead of everything trying to go in one compartment. Now, I'd love that big compartment, but not losing the others, or losing my inside storage.
My under my couch storage is great, also - complete space under couch. I can access it from both inside and outside. So stuff I want easy access to is easy to access from inside. Stuff I use outside, is put near that access point.
I have to say ... when you look at the older rigs, the storage made more sense. IMHO
Oh, this rig comes with a table for in front of the couch. It stores behind the couch - slides right in. And the two chairs (which I've tossed) had a space specifically for them in the overcab area - without taking away space from the queen bed up there - which I turned into storage also.
