I've done motor-homing, but not with such a large group usually.
1. Think 1 and 2 pot meals, all planned in advance. Things like spaghetti sauce over nice noodles (don't have to be spaghetti shaped ones - my kids adored 'drill bit' noodles), Curry over rice, etc. Then pre-measure and pre-mix any of the ingredients that you can, and label it. It might even be worthwhile dehydrating some pre-cooked ingredients, so they take up less space.
2. Consider adding recipes to groups of ingredients, so it's clear what meal the can of whatever belongs to.
3. Definitely plan as much of the week's menu as you can. That doesn't mean you can't leave room for spontaneity - especially if someone catches fresh fish - but having a plan really helps.
4. Pull-in 'helper monkeys' as needed, but send them elsewhere to do the task - like outside on a picnic table to chop a bunch of veggies.
5. Unless the motor home has a better than average kitchen, bring a couple of large rubber tote bins that can be used outside as a dishwashing station. Use a rubber scraper to get as much leftover food off as possible, then do a pre-rinse, then a wash. There's nothing that bugs me more than feeling like all I'm doing is moving around the dirt!
