I know there are some on these forums who say its no problem extending slides when traveling to access the bathroom or kitchen area, but if you don't have to, why?
Now that you've narrowed down your selection, go back again and examine each one with slides IN. Can you function in the camper with slides IN? Do you have access to all the cabinets, or at least most of them without having to extract the slides?
You will find yourself using the camper with slides IN, unless you are parked permanently in one spot and never move. Evidently you have kids, or you would not want the bunks. Can they reach their beds, can you reach your bed? Can you access the refrigerator, stove, other appliances without extracting the slides?
If you plan on camping in extreme heat, one way to cool the camper down faster is to retract the slides until the air conditioner can catch up. During this time, (or if the heat just gets too hot and the air can't keep up), can you and all your family function in the camper with slides IN?
Seriously, go back to each RV candidate and re-explore this question. You may find none of these work very well.
