Practise is the best. But if you are in a hurry I always park with View mode 2 (Key 2). So I get a birds-eye on the truck. If you park with this view you will be able to understand the technique and see what your actions are if you swing to the left or right. As other people already mentioned: left is right and right is left.
Yes it is! You should look at the Options, especially Gameplay you can easely change. So to full automatic, parking positions and many other things more. BUT you need to learn how to drive, and in the beginning you will probably have many chrashes when bumping into cars or difficulties to drive around corners.
When you deliver cargo (whether it is a quick order or consignment market) it is worth parking the trailer in the right place to gain all the EXP points (if you do not want to park it, just press [Enter] - your order will be finished, but your EXP score will be a bit smaller).
It won't park like a passenger car. Most of the time, you should be at a complete stop, completely moving your wheel one way or the other before applying any gas. Then you go very slow and line it up as well as you can. It's still tricky. Personally I just skip self parking because it takes too long and the EXP awards aren't worth it.
