I've heard all the horror stories as well. Avoid it like the plague, but if you need the job, etc. as others have said, take only what you need. If you have windows in your vehicle and allow anything of value to be seen, you may as well send invitations.
I have also heard that vehicles were destroyed "just because...". And I won't go into the details. Sort of a "turf" violation? Something like that. A nice truck may be a sign of prosperity that can motivate one to "bring you down" to the local level a bit.
I had a beater station wagon that allowed me to operate in stealth mode up there. Oh, get the customer to let you use their driveway if they have one.
Oh ya, better to work in daylight hours as well.
Just my experience.
