I had a love-hate relationship with the Sheridan.  Lack of crew protection was a given since it was an armored reconnaissance/airborne assault vehicle (see the earlier post on Sheridans in Desert Shield/Storm).  Automotively, it was terrific and could move like a bat out of hell. Over rough terrain the Christie suspension system could do wonders and not throw a track.  The mechanical issues were in the turret primarily.  It was for its day a sophisticated and sensitive weapons system which did not have an equally sophisticated power generation system from the alternator and voltage regulator.  An all electric drive turret is OK; I think the Centurion has/had one, but you need the proper electrical system to support it.
