GCWR

Open your drivers door and you should find a label either on the B pillar or on the door itself.

The door jamb won't tell Gross Combined Weight Rating, but will tell you Gross Vehicle Weight and Front and Rear axle weight ratings.

GCWR is in the owners manual looking at all your specific cab, drivetrain, and who knows what other things... ;)

Besides, GCWR is just mostly a 'performance' thing and you'll likely exceed your trucks payload long before you come close to the GCWR, especially towing a TT.. ;)

Good luck!

OK, thanks.

Half ton and smaller tend to exceed a couple other ratings well below tow rating when it comes to RVing. I recommend finding out how much payload you have. A CAT scale or landscape supply or city dump would be good to start.

The GCWR is on your owners manual on pages 4-69 through 4-82. You'll need to know how your truck is equipped, engine size and gears. Its lists both towing capacity and GCWR. As already said your payload is listed on the sticker in the door. And the manual also says that your maximum tongue weight allowable is 1000#.

You'll most likely run out your payload and/or tongue capacity well before you hit your towing capacity max. the max towing capacity can be reached if you to a boat or flatbed trailer because they are balanced differently and don't have the heavy tongue weights a TT does.

It should be in your manual. But forget it; it’s likely a useless number. My manual says I can pull about an 8000# TT. But the tw would be far over my remaining payload for my F150. The best numbers will be to load your TV up with all the gear and people you’ll carry on a trip and weigh it. Subtract that from your TV GVWR and you’ll know what you have left to work with. Keep in mind the closer you get to your total payload the harder it will work on any mountain grades. People who pull near max usually wind up getting a bigger TT.
