Agree with a lot of what you guys have said, Maya is pretty much eye candy for tv, with only 3 yrs driving around NYC, she is not even a small bit qualified for that harsh area. They need serious OTR drivers who have spent time on hills, mountains, and in bad weather.
I do enjoy Lisa, she is not bad to look at, a good person, and honestly trying hard to be good at the job. She is pretty much there now with the experience she has gained driving up there.
I didn't watch IRT the first season or two, but kind of find it a good time filler now. Of course, Modern Family is the funniest show on tv, and Pawn Stars is interesting for what you see and can learn.
