When it comes to used pickup trucks, frankly, I defer to experts much wiser than I for explanations of what all those acronyms mean.
I kind explain all of the acronyms around used cars and SUVs readily. But ask me what GAWR, GVWR and GCWR mean and I'm going to get stumped. Well, in the past I would have been stumped but now I can just refer to my article on what GAWR, GVWR and GCWR mean.
That's thanks to the good folks at GMC that I can explain what those terms mean - or at least tell people where to head if they don't understand those terms. (I've always thought myself more like a librarian than an expert when it comes to pickups.)
Pay heed to what those acronyms mean. They can help you avoid buying too little or too much pickup.
