I would have to agree with Proshade, that one of the reasons to allow a tech to take the van home is that when it is at the tech's house, the tools usually are not covered by the company's insurance, but are usually covered by the home owner's insurance. I doubt that to be _the_ MAIN reason, but it is one more factor. I would bet the overall main reason is just that if you have to go to the shop to start your day, you are already about a 1/2 hour behind the guy that just starts driving to the job instead of the shop. And it's the same at the end of the day. it's just more effective.
