What is it?

Thanks for the replies. My thought was maybe the rear spring TSB? My truck has four leafs on each side, but I'm not sure if it always has or if it even applies to a 2014.

 

I believe dealers are required to put them on there for any dealer or port installed add-on that adds weight to the vehicle.

 

The reason it is on there is because the National Traffic and Motor Vehicle Safety Act.
In all technicality, it’s to inform you not to overload your truck. As the owners manual is no longer correct.

See document below for a “sample and reasoning”

 

That's great info. I understand why the Gov't requires this and it's not often a Gov't requirement like this simple sticker gives a person a reason to smile a bit.Thank you for posting it. Like I said, it gives me a chuckle every time I notice it they went to great lengths to advise and warn me my truck has lost 3 kg of carrying capacity or about a paper bag and a half of State of Maine potatoes.
