What you can do with TowCalc: Trailer Weights
- GVWR: the loaded vehicle against its rating, with the payload you have used and what is left.
- GCWR: the vehicle and trailer together against the combined rating, with headroom to spare.
- Tongue weight: the percent on the ball against the healthy 10 to 15 percent target, and the exact weight to aim for.
- Axle and hitch checks: the combined front and rear axle rating, and the hitch tongue and trailer ratings, for a weight carrying or a weight distributing setup.
- Largest trailer: the single biggest trailer this rig can pull, with the weakest link named, whether that is the combined rating, the payload, or the hitch.
- Clear warnings the moment any limit is passed or the tongue is too light or too heavy.
- Metric or imperial throughout: pounds or kilograms.
