Int;l Field Engineer Travel Tips?

ShamelessHero writes: I was recently hired as a Field Engineer, deploying servers, workstations and peripherals to sites around the globe. I try and travel light, but try as I might, the Emergency Repair Kit has ruined three sets of luggage so far.

I know there are Slashdotters here who travel internationally and through some treacherous environs.

What are the best travel tips you've come up with? Recommendations for durable, light yet large luggage are much appreciated.
