Grand Design Solitude vs Solitude s class

there's no much of a difference, for instance even though their site shows a camper fridge in the s-class a residential can still be ordered.

I think if purchasing from a dealer a reduced price and options can be had but if ordering you can get a "solitude" in more floor plans. for example we love the bunk model s class, but add a residential fridge and it's the same as a regular solitude.
