Are you wanting the GVWR or the GCWR?
Since you are looking to pull a trailer I bet you are really looking for the GCWR.
GAWR-front) Gross Axle Weight Rating front axle: max load on the front tires see on the ground (varies D44 or D30)
GAWR-rear) Gross Axle Weight Rating rear axle: max load on the rear tires see on the ground (2 options most years)
GVWR) Gross Vehicle Weight Rating: Total load for the 4 tires on the ground, less then front and rear GAWR added together.
GCWR) Gross Combined Weight Rating: Total weight of vehicle and trailer tires on the ground.
GAWRs and GVWRs are fairly well known. But I don't remember ever seeing a published GCWR rating. Some guesses can be made, but I am not going to do that. I will wait and see if any real number show up first.
