With regards to pay, when my hubby gets home I'll ask him what the rate is.
When my dh was over the road, he was gone 3 weeks, home for 2 or 3 days then gone again for 3 weeks.
It's been a while since dh was driving over the road, but the expenses that I can remember are:
1) Food
2) Showers at truck stops
3) Phone calls, cell or pay phone
4) Laundry, or would you rather do 3 weeks worth in the short time he is home.
5) Entertainment - Beer, internet access, TV.
Has your hubby ever been an over the road truck driver? Does he have a class A?
What are some of the companies that you are looking at? I'll get hubby to tell me if they are goods ones to work for.
Let me tell you, being the wife of an over the road truck driver is HARD! If you can deal with him being gone for 3 or 4 weeks at a stretch and no breaks from the kids, then go for it, other wise, don't. It will put a big strain and stress on both of you. He will want to do nothing but rest when he gets home. Ask me how I know.
