Some generic towing advice -
If you haven't towed before, go slow to begin with, at least until you get the feel of how the car behaves with a trailer behind it. Allow more room to stop, and don't forget to take turns wide so you don't run over something with the trailer wheels - like a gas pump. I'd try making a few short trips, first around town them maybe for a little bit longer before heading off on a long trip so you get some confidence and experience with the combination.
If your car is an auto, make sure it doesn't "hunt' for gears on long grades by shifting it out of high gear manually.
Make sure the car tires
are inflated to the maximum pressure on the sidewalls.
Cross the safety chains under the tongue. The left chain goes to the right side of the car and the right chain goes to the left side of the car. That way, if the trailer comes off the ball, the chains have a chance of catching the tongue before it hits the road. The chains are also affected less by sharp turns when they are hooked up that way.
Stop after going a mile or two and check the safety chains and coupler to make sure all is well. Whenever you stop for gas, check them again, and feel the trailer tires
and hubs to see if they are getting hot. Warm is OK, hot is not. It's not a bad idea to verify your trailer lights
are functioning at the same time.
That's what I can come up with off the top of my head, I'm sure others can add more.
