Hi Tina,
What? Canada getting too cold this time of year? :)

Don't push the weight restriction too far. Your 1st gear/clutch will require you to slip it just a little bit, but no harm. Depending on the steepness of the hills, you may have to go to 3rd - down shift early so that there is no added strain. You could just stay in 3rd all day on the highway, but that eats lots of gasoline.
If you are going Class 2, ensure the tongue weight isn't too great. And give yourself plenty of room to stop. When you get the trailer, take it for a short test drive to make sure the brakes don't lock up on the trailer. Use you left foot on the brake pedal, without moving your right foot, just enough to turn the on brake lights and feel the trailer trying to slow you down.
Remember, when you back up, turn the opposite direction you want the trailer to go :)

Have fun,
Klaus

PS I really don't need that many presents for Christmas that you have to rent a trailer!
