I'd avoid night freight, Stan. You've got a wife and kid at home and in addition to being away from them a lot, the MX and work rules you'll see will scare the living crap out of you. You'll be gone all the time and I'm guessing you'll be asked to break rules that are put in place to keep you alive. You'll be flying poorly maintained equipment with horrible avionics into places that have approaches where you actually want to have an FMS and a moving map.
I'm a huge advocate of flying freight, but consider what kind of freight you get into.
