Make a check list for the cockpit with stuff like this
Arrival: Check for any obstructions overhead and on sides when backing into a site. Fold side mirrors against rig if doable. Place a fool- proof signal flag on steering wheel that reminds you that TV antenna is up.Put receipt on post.
When you get ready to leave: Lower TV antenna, disconnect TV cable, shore power cable, and water hose from utility post and RV and stow before leaving. If you have sewer hose connected,put on sanitary gloves, dump tanks, and shut black and gray valves, rinse sewer hose, let drain and stow it, wash hands. Look all around and under RV and at utility post for your tools, lawn chairs, etc. Check and make sure awning is stowed and locked securely. Pick up any trash or dog waste. Take receipt off post and return at gate if needed, tell gate man that you are leaving. Write down site number for future reference if you liked it.
