I have the WildCat 344QB I guess there's an OK attached to the end because we do have the outside kitchen with the fridge, grill, and stove. We looked at both of these units before buying and chose the WildCat because we felt it offered more user friendly features instead of gadgets and tech stuff. We've got about 20 nights of camping in last year and there's seems to be plenty of space. The island in the kitchen is nice for the extra counter top space and doesn't seem to be in the way.
About this time last year we went camping and had 6 adults and 3 toddlers with us. One of the days the wind was blowing so hard and it was cold enough outside to where it hurt to be out there and all 9 of us stayed in the coach watching movies and listening to the radio and visiting. Before we realized it the day had almost passed and no one was uncomfortable from being in there that long. The couch and dinnet benches are comfortable.
The bunk room has plenty of storage for us. The bunk above the outside kitchen we use for storage for the pack and play sleeper for the one yr old along with toy for the kids to play with. Between the little dresser and the stand-up closet there is enough storage for a 4 day supply of clothing diapers shoes and anything else that you would think of for toddlers. The closet and drawers in the master bedroom had more than enough storage for me and my wife. The shelves I the closet were used to store bath towels and wash rags, so we didn't even store personal items on them.
The pass thru storage is awesome. I have 2 3x5 folding tables in there, folding charcoal grill, several larger toy trucks for the kiddos, a playskol water table for the kids, 10 camping chairs, 2 5x10 rugs, all of my power cords for the coach plus a 20 ft extension for the main power cord, a 50 ft and 25 ft water hose, a 3 gallon fish fried with burner stand and a few other odd and end itemsitems
Bottom line is there's plenty of storage !
