About this chart (4 notes)
  • Rows with a 9,900 lb GVWR are the Canada-only charts, included as printed.
  • Rows marked RamBox are for trucks with the bed storage option.
  • Box-off rows are cab-and-chassis pickups sold without a bed; they use the same engine and axle choices as the pickups.
  • Single and dual rear wheel trucks are listed as separate rows.

Ram camera packages explained

What the numbers mean

Max trailer
The heaviest trailer the configuration is rated to pull, with the right hitch and the vehicle carrying only a driver. Every passenger and every pound of cargo comes off it.
Payload
What the vehicle can carry inside and in the bed, including people and the trailer's tongue or pin weight. It is GVWR minus the vehicle's own weight.
GVWR
Gross vehicle weight rating: the most the loaded vehicle may weigh, itself plus everything in it.
GCWR
Gross combined weight rating: the most the loaded vehicle and loaded trailer may weigh together. It is often the number that runs out first.
Axle ratio
A higher number (3.92 against 3.21) turns the engine faster at a given speed. It costs some fuel economy and usually raises the tow rating.
