I think it depends. I've driven stuff like larger box trucks or pulling a larger trailer (even a tiny house!) without any issue. I wouldn't want to drive them in a city though. That would be stressful.
Just don't get in a hurry. That way you can look far enough ahead to predict any issues before they become pressing. When you're starting out, this also gives you time to remember how the transmission works (although all new rigs are automatics now, which might explain the high schoolers). All the idiots on the street with you can either pass or wait behind.
I agree with this, but it doesn't solve all the issues of driving in the cities (maybe you're area is different). I would be concerned with the narrow streets with people not parked well, double parked, etc. Philly seems to be terrible to drive in compared to many other cities. If you do get into an accident, the police won't even come to make a report. The roads are generally in terrible condition too.
Never drive them into a city. That's one of my rules for operating a larger vehicle; if I can avoid urban/city zones I will. Sometimes you can't avoid them, but the rest of the time I plan to go around. Especially if I'm hauling something heavy.
