Truck-side · Payload · Axles · Hitch

See exactly what your truck can carry — and tow.

Drag passengers into the cab and gear into the bed, then dial in the trailer you intend to pull. Watch front and rear axle loads, GVW, payload remaining, GCW, and hitch capacity react live. Every pound of cargo placement and every pound of tongue weight shows up on the right axle.

WDH improves load distribution but does not prevent sway. Add friction sway control or use an integrated anti-sway WDH (Equal-i-zer, Reese Strait-Line, ProPride) for sway management.
