How we make our calculators and guides

• Sources first: towing and safety figures come from vehicle manufacturers, federal regulations and building codes, and we link to them.
• Show the math: each calculator explains its formula so you can check the result yourself.
• Estimates, not guarantees: your vehicle’s, trailer’s and hitch’s own ratings and labels always come first.
