Towing Limit Pro: Calculator

On many half-ton trucks, payload, not the tow rating, is the limit you hit first.

Towing Limit Pro is free to download. Enter your truck and trailer or RV ratings and see one clear result: Within Capacity, Near Limit or Over Limit.

Enter your truck's ratings straight from the door-jamb sticker. Enter your trailer or RV weights from its label. Accounts for your full load: passengers, cargo, hitch and tongue weight.

Works offline: run every towing calculation with no signal.

AI TOWING ASSISTANT (OPTIONAL SUBSCRIPTION)
Ask questions about your results in plain language. The AI Towing Assistant is a separate subscription and is not included with Basic or with the Expert Mode one-time upgrade. The yearly plan also includes Expert Mode and starts with a 1-week free trial. The AI Towing Assistant needs an internet connection. When you use it, your questions and the towing details you include are sent to a third-party AI provider (OpenAI) to generate answers.

WHAT IT CHECKS
- Payload: how much your truck can carry, including trailer tongue weight
- Tow rating: the most your truck is rated to pull
- GCWR: truck plus trailer combined weight against the rated limit
- Tongue weight: the load your trailer puts on the hitch

HOW IT WORKS
1. Enter your truck's ratings from the door-jamb sticker or your owner's manual.
2. Enter your trailer or RV weights.
3. See your result and which limit is closest.

IMPORTANT
Results are estimates only, based on the numbers you enter; verify with certified scales and your manufacturer's ratings before towing. This app does not determine whether your setup meets any law or regulation.
