That's where it gets interesting. As TFL noted on their YouTube channel while reviewing the JL Wrangler EcoDiesel, the door jamb stickers seem to be off. I've never seen this before on any of the dozens of vehicles I've had, but I thought their discovery with the JL Wrangler was interesting and now my Ram 1500 EcoDiesel is the same way.
GVWR on my truck is 7,200 lbs. Payload is shown at 1,645 lbs. That should give me a curb weight of 5,555 lbs. But, my truck with a half-tank of diesel, 7/8 tank of DEF, small amount of personal belongings inside, and no occupants went 5,420 lbs. on a certified scale.
It's only a 135 lb. difference, but at 10% of trailer weight on the tongue, 135 lbs. can equate to 1,350 lbs. of towing in some conditions, so it's not insignificant.
