Honestly I have no idea. I did a search and did the street view on Google and saw these signs so I called and they transferred me to their transportation person. He said they share the parking structure with the convention center and they have U-hauls, box trucks etc in there all the time. He said a car trailer was no problem..
Ill more than likely be a sheep and just follow the group once I get there. I certainly don't need the headache of getting the truck and trailer in a sticky situation..
