## What is Rigmargin?

Rigmargin is a private RV weight-planning workbench for turning real scale tickets and published equipment ratings into a clear towing picture.

Use the guided three-weigh workflow: truck only, hitched without weight distribution, and hitched with weight distribution. Rigmargin calculates trailer weight, tongue weight and percentage, steer-axle restoration, estimated payload, and remaining margins for the truck, axles, trailer, and combined setup.

KEY FEATURES
- Three-weigh scale-ticket workflow
- Trailer and tongue-weight calculations
- Steer-axle restoration analysis
- Truck, axle, payload, trailer, hitch, tire, and combined margins
- Cargo scenario lab for people, water, gear, and bikes
- Vehicle, trailer, and hitch rating profiles
- Departure checklist
- Local PDF rig report
- Offline field-reference guide
- No account, ads, tracking, analytics, subscription, or network requirement

Rigmargin provides planning estimates from values you enter. Verify every rating and measurement against the vehicle, trailer, tire, hitch, scale ticket, manufacturer guidance, and applicable law before towing. It does not determine whether a combination is legal or safe.
