Viewing Different Results
- The maximum percentage is the initial default.
- You may select different pin weight (PW) or tongue weight (TW) percentages to view possible realistic vehicle towing capacity changes based on available payload.
- In some cases, the realistic vehicle towing capacity may not change on part of, or all of, the percentage scale while selecting different PW/TW percentages. This is because the towing capacity is limited by the GCWR or the TWR. Additional info about GCWR and TWR is available on the glossary page.
- Selecting a higher percentage for a safety margin does not assume the actual TW/PW your trailer will have.
- If you do know the loaded PW/TW percentage of your trailer, you could select the percentage closest to, but not less than, your trailer's PW/TW percentage. For a safer margin, consider increasing the percentage by at least one point.
- To obtain unknown PW/TW percentages of the trailer you own, visit Fifth Wheel Street. and follow the industry leading four-step weight safety plan.
- If all entries were pounds, the results will be in pounds. Likewise, if all entires were kilograms, the results will be in kilograms.
