Park the travel trailer. This can be tricky, as you will need to align the trailer's utility hookups alongside the camp site's utilities. Many sites are back-in, requiring you to maneuver the travel trailer in reverse. If you have a passenger, ask him or her to get out and act as a spotter.
Set the parking brake in the towing vehicle when you are happy with the trailer's location, and place the wheel chocks. One chock goes in front of the front tire and one goes behind the back tire. Chocks can be placed on either side of the trailer.
Remove the chains, the electrical pigtail that is connected to the tow vehicle and the emergency brake cord.
Remove the anti-sway system that attaches to the trailer hitch and helps stabilize the trailer for travel. Refer to the manufacturer's instructions, as each anti-sway system is slightly different. You may need to use the tongue jack to significantly raise the height of the trailer tongue.
Lower the trailer tongue until the travel trailer's weight is fully resting on the vehicle hitch. This releases tension and enhances safety.
Use the tongue jack to lower the trailer tongue foot, raising the trailer tongue. At the same time, release the mechanism that connects the trailer to the tow vehicle's hitch. The hitch will drop down away from the trailer.
Drive the tow vehicle forward or move it out of the way.
Level the travel trailer. You may have automatic or manual leveling legs. Some RV owners place pieces of wood or plastic leveling blocks underneath these legs. Use the tongue jack to raise or lower the front end of the trailer as needed.
