Pros
I never get hassled about travel arrangements. I typically stay at any hotels I like within reason, fly the airlines I like and always get a decent per diem. When you travel for a living, this is a big deal! Management and teammates are typically high quality. The job has the potential to expose you to many elements of the IT world (given its Microsoft based). Lots of paid training time (80 hours a year) and the company also pays for all Microsoft Certifications (they pay for two tries per exam). There is an opportunity to rise in the company quickly, with each promotion carrying 10-15% increases in pay typically.
Cons
The job is ALL TRAVEL! If you don't like travelling, this job isn't for you. Some projects just stink and you can do little but gut it out and hope to be on to the next soon. Every project has a new boss, some are good, some are bad. In my experience they tend to be decent or better.
