Check the whole towing setup, not just one number.
TowAtlas brings the most important towing calculations together for pickups, travel trailers, fifth wheels and RVs — payload, loaded trailer weight, tongue or pin weight, GCWR, axle limits, hitch limits and real scale weights.
Which towing calculator do you need?
If you are checking a truck and trailer combination, start with Rig Check. Use the focused calculators when you need one specific answer.
Full Towing / Rig Check
Compare payload, tow rating, GVWR, GCWR, hitch and axle limits together.
Payload Calculator
See how passengers, cargo, hitch hardware and tongue or pin weight use truck payload.
Trailer Weight Calculator
Estimate realistic loaded trailer weight from dry weight, water, propane, batteries and cargo.
Fifth-Wheel Pin Weight
Estimate loaded pin weight and its effect on truck payload.
CAT Scale Calculator
Use real axle weights to evaluate loaded trailer weight, tongue weight and WDH performance.
GCWR / Combined Weight
Compare estimated combined loaded weight with the GCWR you enter.
A towing calculator should check more than max tow rating
A truck can be below its advertised maximum towing capacity and still be overloaded. The most common reason is that trailer tongue or fifth-wheel pin weight, passengers, cargo and hitch hardware consume the truck's payload before the trailer reaches the advertised tow limit.
A complete towing check should compare the exact truck and trailer against every applicable rating: payload, truck GVWR, front and rear axle ratings, tire ratings, receiver or fifth-wheel hitch ratings, trailer GVWR and GCWR where the manufacturer publishes one.
TowAtlas is built around that full-picture approach. Use estimates when planning, then replace them with actual loaded weights and scale measurements whenever possible.
How to check a truck and trailer
Start with ratings for the actual cab, bed, engine, drivetrain and equipment configuration.
Do not rely only on brochure dry weight. Include water, propane, batteries and travel cargo.
Subtract passengers, cargo, hitch hardware and tongue or pin weight from available payload.
Compare GVWR, GCWR, axles, tires, hitch and trailer limits rather than relying on one number.
Real loaded axle weights are better than estimates and can reveal distribution issues.
Once the numbers work, use the Pre-Tow Safety Checklist before you move.

Towing Capacity vs Payload
Why payload often becomes the limiting factor first.
Travel Trailer Tongue Weight
Understand loaded tongue weight and its effect on the truck.
Dry Weight vs GVWR
Know which trailer number is a starting point, a limit and the real loaded weight.
Read a CAT Scale Ticket
Understand steer, drive and trailer axle lines before comparing ratings.
Pre-Tow Safety Checklist
Run the repeatable departure check after the towing numbers are verified.
Towing calculator FAQ
What is the best way to calculate whether my truck can tow a trailer?
Check the exact truck and loaded trailer against payload, tow rating, GVWR, GCWR where applicable, axle ratings, tire ratings and hitch limits together. A max tow rating by itself is not enough.
Should I use trailer dry weight?
Use actual loaded weight when possible. If you do not have a scale weight yet, build a realistic loaded estimate that includes water, propane, batteries, food, tools and cargo.
Does tongue weight count against payload?
Yes. Tongue or fifth-wheel pin weight is supported by the truck and uses available payload along with passengers, cargo and hitch hardware.
