HitchMargin’s payload calculator
A free RV towing calculator estimates payload remaining after trailer tongue weight, hitch hardware, passengers, and truck cargo.
- For
- RV drivers checking truck-and-trailer payload
- Worth noticing
- It tells users to enter trailer GVWR rather than dry weight, and flags rear GAWR and hitch ratings for separate checks.
Field notes
The calculator takes trailer GVWR, tongue-weight percentage, hitch weight, occupants, cargo, and the truck’s door-jamb payload, then subtracts the estimated load. Its example uses a 7,500-pound trailer and returns 75 pounds remaining; the page says a negative result means payload is exceeded on paper. The surrounding data board lists RV equipment comparisons and guides with update dates, while separately advising users to check rear GAWR and hitch ratings and confirm weights on a scale.
