Connect and check security of safety chains or cables and breakaway switch.
Plug in the electrical connector on the trailer to the tow vehicle.
Check operation of all lights and the brake system.
Inspect tires for proper inflation, adequate tread, and even wear.
Check that the spare tire is the correct size (tire, wheel bolt pattern and lug nuts) and is properly inflated.
Check that all lug nuts are tight.
Inspect the floor for weak spots.
Inspect security and strength of all tie rings and trailer ties.
Adjust roof vents and windows for proper ventilation.
Check all partitions and posts to ensure they are pinned or fastened in place.
Open escape doors to allow quick exit while loading.
Load animals.
Put all breast and butt bars in place and close and secure all doors.
Check the electrical connection between the trailer and the tow vehicle and that the coupler is securely locked onto the tow vehicle.
