Human Factors
Captain was the Pilot Flying. On the landing roll-out on Runway XX in ZZZ he noticed a fuel truck attempting to cross the runway on Taxiway XX. I was heads down monitoring the airspeed; around my '80' call out the Captain said...'That's a fuel truck'. I was unable to see it because of the windshield divider. He immediately applied full brakes and full reversers and we managed to come to a complete stop within 100 ft of the truck.The sound of the brakes screeching and reversers caused the driver to slow to a stop. He still managed to make it past the driver side door onto the runway. I made another CTAF call announcing we were on the runway still...there was no acknowledgment from the fuel truck. He backed up allowed us to continue down to Taxiway XY; then he crossed the runway on XX. I continued to make CTAF traffic calls and never heard the fuel truck make a single one while he continued to the side of the runway.I believe the fuel truck was not monitoring the CTAF frequency. We were switched from approach to advisory frequency well beyond 5 miles from the runway landing zone. Even after the event occurred we still did not hear him make any calls as he continued driving across the airport taxiways.Ground personnel should be trained to constantly monitor CTAF; Ground; Tower and ramp frequencies at all times when moving in vehicles around the airport.
Air carrier First Officer reported a max effort stop was required on the landing roll to avoid a collision with a truck crossing the runway.
