Tow rating is one limit — payload is what overloads first
The full calculator factors in:
Tongue weight vs payload
Water tanks (50 gal = 417 lbs)
Propane (40 lbs full)
Passengers in truck
Gear, bikes, coolers, tools
Cargo weight distribution
Your truck's payload limit carries tongue weight, passengers, and everything in the bed — that's the number that overloads first. The calculator checks both tow and payload with real gear weights.
