SteadyTow shows you exactly how your cargo affects weight distribution, tongue weight, and towing safety — before you leave the driveway.
Free to use. Pro features available.
Overloaded axles. Bad tongue weight. Cargo shifting on the highway. Most trailer loading problems happen because there's no easy way to check your setup before you drive. SteadyTow changes that.
See how every item affects tongue weight, axle loads, and towing capacity as you build your load. Uses moment-balance physics with support for single, tandem, and triple axle trailers.
Drag and drop cargo on a top-down trailer view. See exactly where each item sits and how it affects balance.
Know how many tie-downs you need and where. Analyzes braking and lateral forces using FMCSA-based standards.
Get warnings for overloaded axles, dangerous tongue weight, hitch mismatches, and under-secured cargo.
Enter your VIN and SteadyTow pulls your tow vehicle's ratings directly from the NHTSA database. No manual lookups or guessing required.
All calculations happen on your device. No account required. No data uploaded. Available wherever you are.
