Gvwr:
Gross Vehicle Weight Rating varied significantly based on configuration, ranging from approximately 6,200 lbs to over 10,000 lbs for heavy-duty models.
Crash Test Results:
Limited specific official crash test ratings available for this era of heavy-duty trucks. Focus was on structural integrity and payload capacity.
