Proceed with caution swagger.
I am away from home 100-120 nights per year. I'm sitting in a hetel romm right now. A few points to consider. You WILL find it very difficult to get things done at home. You will find it difficult to make plans with friends and family and keep them. You'll miss birthdays, anniversaries, holidays, etc. It helps if your single, but what really matters is that you are prepared to make some big sacrifices to get the job done for the customer. We commonly put in 70-80+ hours weeks in the initial start-up phase of a project.
Now for the positives. You can easily increase your salary by 75-100% or more depending on your companies compensation plan (just don't blow it all on steak dinners and bar tabs when your travelling...don't laugh I know people who have been doing it for years). You will be able to generate a list of contacts/aquaintances in your industry that will make the salemen in your comapny green with envy. I'm confident that if I had to leave my position with my current employer, I could find another within a day. And you will gain a lot of experience - fast.
It's not a decision to be taken lightly. If you have a family, they MUST be 100% on board.
Hope this helps
