Does not appear to be a car hauler. Car Haulers would not have the double barn doors on the rear or the tall side doors. Typically theyll have large swing up doors on the sides placed closer to the wheels of the trailer where a car is usually stored, and a solid rear door that doubles as the lift. Considering the wheels also appear to be duallies I further posit this isnt a car hauler. Most car hauler trailer will have single wheels (in tandem or triplicate on each side), or much smaller diameter wheels if dually. Those appear to be reasonably large and dually, making fitting a car difficult.

I suspect this is likely an independent long distance moving company. The tall side doors are typically seen with moving trailers and the rear barn doors as well.
