Sorry, but here comes more questions?
Does Mrs. Buckle work?
Does the lodging provided you to do your own cooking, laundry and such or will you be eating out and stuff all the time?
Does the new employer pay for any meals or other expenses?
Are you an employee of this company or working as a sub-contractor? Do you get any insurance (medical, dental, vision, life, STD/LTD)?
A lot of my questions are based on monitary considerations. In my line of work, the client pays for "Usual and Customary" travel related expenses. In general (and historically speaking), these expenses average approximately $1,000 per week. I guess what I'm saying is to sit down and compute your out-of-pocket expenses and subtract that from the compensation package.
Other pros & cons.
Con You haven't said how you'll be traveling but if by car, remember 2 days of your 2-weeks off will be spent traveling. If by air, you have even more expenses (airfare, car rental, airport parking).
Pro you do get 2 weeks off. You haven't said, but does this 26-week/year opportunity offer a salary similar to a full years compensation? In the 2 weeks you're home, hopefully you can address any preventative maintenance to assure the weeks you're gone are event-free.
Something else to ponder. It's not unusual to either have time or money. It's less common to have both at the same time. Will this job offer you the capability of having both? Without projects (which normally require $$$), those 2 weeks off may be boring.
In general, I had no real issues with travel and often enjoyed it. Most of my travel was M-F so I was almost always home on weekends. Most of my travel was almost by air, so I did rack up the frequent flyer miles. On occasion, Mrs. Zoom would join me if I was going to a nice destination. FF miles to get her there and after that, the only expense was her food (and her SHOPPING while I was at work). It made for nice little vacations for us.
I do travel significantly less now. It's somewhat based on client needs but I also set my rates based on travel requirements. If the travel is little-to-none, I offer them a better rate (which they normally take). For 50% travel, I put a premium on my blended rate (basically, they're paying the premium even on the days I'm at home). This "premium" is for inconvenience to myself as well as my family. I would have to put my daughter in a before and after school program and other monetary inconveniences. If they want me at their site all the time, I just pass on the job.
More later (but I'd better get back to work)
