1 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.

2 GCWR: The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer. A properly equipped tow vehicle and trailer at the maximum GCWR should be able to accelerate and merge with traffic, climb typical interstate grades at highway speeds, handle the combination on virtually all road surfaces and stop adequately within a reasonable distance.

3 Trailer tongue weight should be 10 to 15 percent of total loaded trailer weight (up to 750 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. Base cooling system includes all content required to attain maximum trailer rating. No optional cooling equipment available.
