- Maximum trailer weight ratings are calculated assuming a base vehicle, except for any option(s) necessary to achieve the rating, plus driver. The weight of other optional equipment, passengers and cargo will reduce the maximum trailer weight your vehicle can tow. See your Chevy dealer for additional details. NOTES: Trailer tongue weight should be 10 to 15 percent of total loaded trailer weight (up to 1,000 lbs.). Addition of trailer tongue weight cannot cause vehicle weights to exceed Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR). These ratings can be found on the certification label located on the driver door or door frame. For recreational towing restrictions and availability, consult the Owner’s Manual.
