It gives me peace of mind to see the pilot and co-pilot review their checklists before we take off in an airplane. You know that they are not going to forget to do something, like fuel the plane or make sure all the doors are locked. Having checklists for your trailer is akin to this. You aren’t going to forget to fill your water tank or make sure everything is stowed before you depart.
Over the years I have developed checklists. I have one for beginning of the season, end of the season, departure from home, arrival at a campsite, departure from a campsite, and arrival at home. Each one has it’s unique items that need to be performed
Beginning and End of the Season
These two checklists are less extensive than the trip related ones, but they serve as a beginning and end to the trip related checklists.
The trailer batteries stored for winter on maintainers. 
Nothing hanging on the ground. 
Bathroom cleaned out of all items.
Beginning of Season — also known as Trailer De-Winterization
- Mostly concerned with getting the water system back in operation for the season
- Returns the batteries to the trailer from storage
- Restocks the trailer from the inside storage and replacement items purchased
- Cleaning
End of Season — Trailer Winterization
- Draining and winterizing the water system
- Removing the batteries to inside storage
- Removing items that should not freeze or could become nests for pests entering the trailer
- Cleaning
Trip Preparation and Completion
Getting the trailer ready for a trip or cleaning up after arrival at home are full of tasks that could be easily overlooked.

Detachable electrical cable 
Twist tie closure
Pre-Trip
- Assuring that everything is operational before being away from home
- Fill fresh water tank and provision trailer
- Stow clothing and other items that are removed after each trip.
Post-Trip
- Situating trailer for storage
- Removing all items that should not remain in the trailer between trips
- General cleanup
Campsite arrival and departure
The setup and take down of the campsite can make a big difference in enjoying the stay. Missing something upon departure can sometimes be felt at the next campsite. For example, forgetting an item at one site means that it is not available at the next site.
Chairs stowed for travel

Campsite Arrival
- Leveling, unhitching, and stabilizing the trailer
- Setting up tables, chairs and other amenities
- Hooking up to available utilities, if any
Campsite Departure
- Disconnecting utilities
- Putting away amenities, tables, chairs, and everything else that was dragged out
- Hitching up to drive away
