Find a good checklist. Modify it to your needs. Use it always!
Take it slow. If you have to hurry, have your co-pilot make a call that you'll be late. You will never see the guy who is trying to rush you again and they are prolly just jealous you are doing recreation.
Always drive first, then navigate, then worry about OS like cell phone, scanning your radio into a death metal/rap/country station, where you packed the snacks, etc.
Backing up is a lot easier if you have your signals worked out before hand with your spotter. Practice with a toy trailer and have your partner work with you.
Once a the CG you'll find there is always someone willing to help. Heck the managers can usually get a rig into a site that average campers think was impossible, without much effort.
Most importantly - have fun!
