We did look at, and liked, both floor plans, but went with 21ss for the huge amount of floor space. A lot of people consider that as just wasted space and prefer the 23ss, which has way more storage space and a little more counter top space. For us the "open" feeling of the 21ss is what we loved. I feel claustrophobic in most small campers, but with the 21ss it feels more like you are in a small room than in a camper. That is what tipped the scales for us, especially since we camp with our 5 dogs. As for the storage space, the 21ss has more than enough for the DW, DS, and myself. You just have to figure out how to best utilize the space you have. Over the last two years we have pretty much tweaked that to meet our needs. Frankly with just the 3 of us (8 if you count the beasts) we probably would have a lot of unused storage in the 23ss; however, add just more human and I can totally see the 23ss or the 233s being the better choice. As for the counter top space, it would be nice to have a little more, but it really does not matter because we always cook outside anyway. We only use the stove top for the coffee and the oven for biscuits. They both are great floor plans. You just have to weigh what attributes are more important to you.
