Ask anything you want, I did OTR for three years and there are huge plusses and minuses to it.
Plusses:
I traveled all over 12 states and four Canadian provinces and saw a lot of country most people will never see.
The freedom of the road is nothing like a 9-5 daily grind.
There's nothing quite like rolling through a small town on a summer night in a lit up large car and having tons of kids wanting you to honk your horn. Haha
I met a lot of different people in my OTR time, made a lot of great friends too.
Minuses:
You will miss out on family events, its even worse if you have kids.
You will miss anniversaries, birthdays, some holidays, etc etc
You will have to drive long hours on bad roads or fight bad conditions to deliver loads on time.
You will have to live off chitty truck stop food.
DOT regulations......'nuff said on that.
Pay sucks for the hours you put in.
Getting sick on the road is one of the worst things I've ever had to deal with.
Having a relationship over the phone for weeks on end gets tough.
There's a lot more to both sides of the coin, but that's my insight into the matter.
