Two tips:
1. Make labels with your tow and TT license #'s. One goes in your wallet, the other goes on the dash. Saves time and running around.
2. If your eyes are decent, mount a 4" Hoppy type level on the front drivers side of your TT. You should be able to read the bubble with the side, rear view mirror. At night, touch the brake and the bubble will light up. When about to park, watch for a level or closer to level spot. If using stepped blocks, you can pull up or back untill level. No getting in and out to check.
