We have a NCO model and have learned to adjust how we move inside. Rule #1. Only 1 person stands at a time. Rule #2. When you are dressed, get out of the way so the other person has room to get dressed. Instead of putting excess gear and bedding on the CO section, you have to roll the sleeping bags and put them in the truck so you have room to erect the table. Kind of difficult at first, but it makes for a neat and tidy looking camper inside.
The bottom line is this. If I had a larger capacity truck, I would have a CO.
