WeRV Tow Confidence · Free tool

Scan your truck.
Know your limits.

Enter a VIN or your truck's year, make and model. We'll look for a reviewed rating that matches its configuration, then compare it with the rental. If we can't confirm the rating, we'll point you to the manufacturer guide instead of guessing.

No email or fee. Your truck's labels and equipment still matter for a safe match.
