Common questions

Where do I find my truck's ratings?

Most are on the stickers inside the driver's door frame. The yellow Tire and Loading sticker lists payload. The white certification label lists GVWR and the front and rear axle ratings (GAWR FRT and GAWR RR). Tow rating and GCWR are in your owner's manual or the manufacturer's towing guide.

The dealer said my truck can tow it. Why does Towdini say it's tight?

Dealers usually quote the maximum tow rating. Payload, the hitch, or the rear axle almost always run out first, especially once people, gear, and the trailer's tongue or pin weight are in the truck. Towdini checks all of them.

Does Towdini work for fifth wheels and goosenecks?

Yes. Choose "Fifth wheel or gooseneck" at the top of the Check screen, and Towdini uses pin weight, your fifth-wheel tow rating, and your hitch's ratings.

Is my information saved anywhere?
