The biggest issue in driving on city streets is the dreaded Right Turn. Swing wide to the left before the turn..(even into the opposing lane if you can do that safely) and use the entire road after you make the turn. Many time a street corner will have a sign, a street light, A tree, a group of pedestrians waiting to cross, or something else stuck very close to the road at the corner. A right hand turn, you need to swing wide to get your trailer around that obstacle. If you need to wait for traffic to clear before you can use the opposing lanes....just wait. Put your "hater blockers" on. While most other drivers will be helpful. There is always one that wants to demonstrate his importance to you.
I have been in situations where a GPS has put me into a dead end street. Had to back up a half mile to get turned around. Curvy road with cars parked on both sides. People came out of their houses to watch the fun. Kids riding around the street on bikes. I had DW outside with her radio, guiding me back. This is where you take a deep breath and say..."OK calm down. Relax, and we'll get through this." Then go back to the basics and take your time. Slow and steady wins the race. Took us 45 minutes. But we escaped. I learned not to ALWAYS trust the GPS.
