" I never had a problem with UPS, but it seems a lot of guys do, mostly with loss and theft claims, and that concerns me."

As do I,what seems to be the issue is three fold, they outsource insurance-to Crawford &Co,they also consider insurance a profit center-like the fuel surcharge,and the employees are union-teamsters and very hard to fire for theft.
A GOOG search of just Crawford and Company UPS brings lots of pages of theft, claim denials;
