You won't be bothered by weirdos asking for money, because security is on top of all that. Assuming by "truck" you mean a big rig, because sleeping in personal vehicles is not permitted. You might get away with a cat nap in the gas station parking lot, but not in the parking structure nor main lots.
The trucks are parked next to the original casino, which I like to visit and when I drive in there I see alot of trucks but I have never seen people wandering around them.
Be pro and respectful and they should leave you in peace. Dont forget to patronize that's why they want you there.
I don't think so. I saw security monitoring the parking lot. I had no problem whatsoever. Just a short walk to the casino and they have a bowling alley which I enjoyed. Their are also a small food court in the casino that has a Panda Express, Burger joint, and an Italian pizza place that has lasagna, calzones, and Stromboli. Chipotle, In and out Burger, and other restaurants a short walk away.
