Details in the Door Jamb

If you get a chance to look at the inner frame of your drivers’ door and you’ll likely notice a sticker better known as the door jamb sticker. You might even find a few stickers depending on the year, make, and model. Regardless, the information on the door jamb stickers is critical in helping you understand some highly relevant data points about the Ram 1500’s tires, towing, trailering, and performance information.

VIN Details – You’ll likely see the Vehicle Identification Number (VIN) and complementary details. The VIN is the unique number that only this specific Ram 1500 has, and it can be used to look up important details such as title and ownership information. You’ll also find some related numbers or names on this sticker, such as the paint type and the trim type. The paint type is important so you can do an exact match for any touch-ups or repairs to the Ram 1500’s exterior finish. The trim level is also displayed to show you the version of your Ram 1500 and the features that were on it at the time of manufacture, so you know what was original.

Weight Details – An important number you’ll find on a door jamb decal is going to be numbers that describe the Ram 1500’s gross vehicle weight rating, likely listed as the GVWR on the sticker. This weight factors in a full tank of gas, the maximum number of passengers, and the maximum amount of cargo. Exceeding the maximum GVWR can result in mechanical failures that could put everyone in the truck and on the road at risk, so pay attention to this data point.

Tire Details – The door jamb stickers will also tip you to important facts about the tires you should use when operating your Ram 1500. You’ll see information about the size and dimensions of the tires and the proper PSI level that each tire should be inflated to so your truck will drive safe and smooth.

Trailering Details – In addition to the GVWR described above, which is an overall figure for the vehicle, there are additional numbers worthy of your attention when using the Ram 1500 for serious towing and trailering. One is the Gross Axle Weighing Rating (GAWR). GAWR represents the maximum weight an individual axle can support.

Other items that may be apparent in the door jamb would be the payload, which is how much additional cargo weight you can add beyond what the truck weighs on its own. This is a simple yet useful number to approximate what you can safely carry as payload. The Towing Capacity is another number that will be super useful and is specific to trailering. This is the maximum pounds the truck can safely tow behind it. It is a factor of the aforementioned GVWR and GAWR numbers.

Finally, there is the Gross Combined Weight Rating or GCWR. This is the largest number you’ll likely see on the door jamb or in Ram 1500 specs. This is the maximum weight when the truck is at its maximum payload and maximum towing capacities. So, don’t exceed GCWR; that’s pretty important.

The official Ram 1500 specs will tell you a lot of the basics. For example, a 2021 Ram 1500 Tradesman has a GVWR of 7,100 pounds, a payload capacity of 2,320 pounds, a towing capacity of 7,740 pounds, and a GCWR of 12,900 pounds. However, those are maximum specs for the model, and your particular used truck will have different numbers depending on how it was options. So look in the door jamb instead of just reading the official manufacturer specs.

Does the Door Seal the Deal?

While the door jamb has a wealth of information, Ram also recognizes that the average truck buyer may not have the time or expertise to decipher all of this information. Given information about tire pressure and towing weight are pretty important to vehicle and people safety, Ram created a cool website where you can simply type in the VIN and find the specific payload and towing ratings for that specific Ram 1500.

Just go to the Ram Towing Capacity Guide, and there will be a pop-up box to enter the specific VIN when clicking “look up my vehicle.” This site also has tons of general information about towing and trailering with a Ram, including towing technologies you can use and the engine performance when towing. If you plan to do some serious hauling, such as a boat, RV, or camper, be sure to check out this useful site.
