Yes their is truck parking lots of room
I would check at the RV area by the gas station as there's some parking along that road where the fireworks stands are. Call the casino and see what they say.
no there is not a parking garage for semi truck yet they might let you park across the street from the casino at the hotel there's RV parking they may allow a big rig to park there
There is a newer parking garage on the east side and the original parking lot on the west side. I can't remember if there is room for a tractor trailer. I'd call ahead, they have an associate lot they may be willing to let you park and shuttle you back and forth.
