US towing and payload planning
TowLoad Guide compares people, cargo, hitch hardware, and trailer weight with the manufacturer limits you select or enter. It shows each available margin and leaves a check unresolved when a required value is missing.
One worksheet, separate limits
Enter loaded weights and available ratings to see signed margins for payload, towing, GVWR, GCWR, and hitch or tongue limits without hiding unknowns behind one score.
Choose a published configuration to fill only the ratings supported by its source. Current verified coverage includes conventional-towing data for the 2025 Chevrolet Silverado 1500, 2026 Ford F-150, 2026 Ram 1500, and 2026 GMC Sierra 1500.
The occupant-and-cargo label on your vehicle is more specific than a generic configuration reference. Use the label override when that value is available.
A positive or negative margin applies only to the limit checked. Missing payload, GVWR, curb-weight, or hitch information stays visibly Not checked.
Verified reference coverage
The 2025 Silverado reference preserves 51 configurations and 102 ratings. The 2026 F-150 reference preserves 63 physical configurations, 65 contexts, and 130 observations. The 2026 Ram 1500 reference preserves 26 physical configurations, 27 contexts, and 54 observations. The 2026 Sierra 1500 reference preserves 23 physical configurations, 54 contexts, and 108 observations. Multi-context configurations remain explicit.
Review the 2025 Silverado 1500 ratings, review the 2026 F-150 ratings, review the 2026 Ram 1500 ratings, or review the 2026 Sierra 1500 ratings.
Traceable by design
Vehicle data passes source transcription, schema checks, independent row review, and a fail-closed publication gate before appearing in the selector or reference page.
Read the vehicle-data and calculation methodology, including how corrections are handled.
Read the source policy and current Chevrolet, Ford, and Ram source records, including revision and reconciliation caveats.
Understand the numbers
These source-reviewed guides separate trailer, payload, vehicle, combination, and axle limits before you enter a scenario.
See why a trailer can be below its entered tow rating while the truck is above its payload rating.
Follow tongue load through payload arithmetic without counting it twice in a hitched scale measurement.
Match each manufacturer rating with the actual loaded weight needed for that comparison.
Common questions
No. Ratings can differ by cab, bed, drivetrain, engine, package, wheels, trim, equipment, and loading. Match the complete configuration and confirm the exact vehicle documentation.
Passengers, cargo, accessories, hitch hardware, and trailer tongue or pin weight all consume available payload. A trailer can be below a tow rating while another applicable limit is closer.
Leave it unknown. TowLoad Guide marks the dependent result Not checked instead of substituting zero or an estimate. Vehicle labels, the Owner's Manual, manufacturer guides, and loaded scale weights can supply more-specific inputs.
No. Results compare arithmetic inputs with selected or entered limits. They do not account for every equipment, loading, mechanical, road, weather, driver, or jurisdiction factor.
