Some Ram camera packages include cameras, while others only add the wiring or a digital mirror. See what each option code, from XAK to XH7, actually adds.
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.
