I very rarely touched a box after getting into the Metro/1900. In the chieftain I can't recall ever lifting a sac o checks that was heavy enough to cause any hernias/back problems. Don't let the negative whiners sway you from a good job. Its what you make it; if you're positive you'll leave there with some good experience and probably even miss it. BTW, I lift much heavier pieces of luggage flying corporate jets than any boxes I ever lifted at AMF. Is that a reason for me to be negative about my current job? Hell no...
