We used to have a motor home and now we have a trailer. When we camp locally i love getting there and setting up by myself. On the long trips it usually starts a fight with my better half. I've got my own routine/set up procedure id rather do by myself. plus you get the extra hour or so to yourself before everyone shows up. its nice to have everything set up for when the rest of the group arrives.
The worst is with a group full of old timers. You end up with too many people giving orders. Not enough people working lol.
