TOWCHECK FIELD GUIDE
Dry weight vs. loaded trailer weight
Dry or unloaded weight is rarely the weight actually towed. The travel-ready number may add factory options not included in the published figure, batteries, propane, water, food, tools, clothing and recreational cargo.
What the terms mean
Unloaded vehicle weight conventions vary by manufacturer. Trailer GVWR is the maximum rated loaded weight; it is not automatically the predicted travel weight. Cargo carrying capacity is consumed by every added item and fluid.
Worked example
Common mistakes
- Comparing tow rating only with brochure dry weight
- Assuming every factory option is in the advertised figure
- Forgetting dealer-installed equipment and liquids
Frequently asked questions

What number should replace the estimate?
A measurement of the loaded trailer or combination in the condition being evaluated.
