One problem related to rearview mirror has been reported for the 2001 Dodge RAM. The most recently reported issues are listed below.
Drivers side and passengers side mirrors shake/vibrate at highway speeds making it difficult to see approaching traffic. Eventually this will cause a accident. I returned the vechicle to the dealer and had the drivers side mirrior replaced but this replacement suffered from the same shaking problems at highway speeds. I told the service rep. But he said they all ( Dodge pickups 1500-2500 series) suffer from the same problem and they are waiting for a TSB on the problem. I also have a friend with the same truck and the same problem.
