Rigmargin: RV Weight Planner
Scale Tickets & Tow Margins
$0.99 · Designed for iPad. Not verified for macOS.
Turn three real scale readings into an explainable towing picture, test cargo changes, and review practical margins before departure.
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
