If the compressor is noisy you most likely have a leak. It shouldn't really be noticeable if the truck is running.
In addition to stamp's questions pay attention to the ride height after the truck sits. It might not be that much lower than the lowered entry/exit height so pay attention to the height after it vents when you park it at night to where it is in the morning.
