About CheckMyTow

Ask “how much can my truck tow?” and most answers give you a single big number — the manufacturer's best-case max. But that number assumes a specific engine, axle ratio, and package, an empty cab, and a stripped trailer. Change any of those and the real limit drops, often a lot. On half-ton trucks the number that actually stops you is usually payload, not the tow rating.

CheckMyTow exists to fix that. We do three things differently:

• Config-level, not model-level. We source numbers by engine × transmission × axle ratio × cab × tow package from manufacturer towing guides — the detail most lookups flatten into one figure.
• We name the limiting factor. Our calculator checks all four limits — tow rating, GCWR, payload, and hitch class — against your real load and tells you which one binds first.
• The reverse question, too. Not just “what can this truck tow?” but “what can safely tow the trailer I want?” — the reverse matcher.

Every number is sourced, cross-checked, and graded — see the methodology and data sources. The site is edited by Kirill Dvoryashin. Results are planning estimates; always confirm your vehicle's ratings before towing (disclaimer).
