Agree with all the others about each truck doing it's own thing, far easier and has worked well for us. Also agree with eating together as a group if possible. We take a table for 4 when travelling with others to help with this. Happy hour is a must for reliving the days adventures, if you get into camp early enough.
Just to watch the mouths drool however, get yourself some quick practice at making bread or damper, and when you have a 2 night stop, get the camp oven going. I can guarantee that you won't be eating it alone. Also there is a great recipe on MySwag for bush donuts that goes down a treat with both young and old.
My only other bit of advice in case you haven't run too many trips, is to clearly state the departure time for the next morning (lunch durations, photo stops, etc). You don't have to be a time Nazi, but by doing this it can remove a lot of frustration from group travel. I have seen both sides of this, and have ended up arriving at the next nights camp very late by just frittering away time that you don't notice.
