You will be missing more of your family being on the road than you do now with 9-5.
Benefits, especially insurance, will be a big change for you and your family.
As the outages get shorter, the less experienced get less work....
Advancement (from your current level) may be more challenging on the road. There are different opportunities than you get as a house mouse. House people get training, usually paid for by the company. Roadies pay for it on their own.
If money isn't a problem, work as little OT as possible, get involved in things outside of work. Scouts, Church, Coach - these things can bust the routine, and give you a focus beyond your wants and needs to those of others.
I have been house, and roadie. I got off the road when my kids were born, haven't regretted it one second. Seeing my kids every day, meeting their teachers, attending the sports events, class plays, scout trips, etc is something that enriches me. I would rather be a greeter at Walmart than to be away from my family. But, luckily, my job is a pretty good one, and I have learned to accept the routine parts of it.
Good luck with your decision.
