A practical planning range
For conventional travel trailers, a commonly used planning range is roughly 10% to 15% of the trailer's loaded weight on the tongue. Treat that as a starting point, not a substitute for the exact trailer, hitch and tow vehicle manufacturer requirements.
Example
If a travel trailer weighs 7,000 lb loaded, 10% is about 700 lb, 12% is about 840 lb and 15% is about 1,050 lb. That tongue load is carried by the tow vehicle and needs to fit within payload, rear axle, receiver and hitch limits.
Why loaded weight matters
Dry trailer weight does not tell you the final tongue weight. Water, propane, batteries, food, tools and camping gear can change both total trailer weight and weight distribution. Where that cargo sits matters too.
Too little tongue weight
An improperly loaded trailer with insufficient tongue weight can be more prone to instability or sway. Do not try to solve sway by moving weight blindly; load the trailer according to manufacturer guidance and verify the entire setup.
Too much tongue weight
More tongue weight can consume truck payload quickly and increase rear axle and hitch load. A trailer can be below the advertised tow rating while the truck is already at or over payload or axle limits.
How to verify tongue weight
A purpose-built tongue-weight scale can be useful, and a multi-weigh CAT Scale process can estimate tongue weight while also showing steer, drive and trailer axle changes.
Frequently asked questions
What percentage should travel trailer tongue weight be?
A commonly used planning range for conventional travel trailers is about 10% to 15% of loaded trailer weight, but follow the exact manufacturer guidance for the trailer and hitch.
Does tongue weight count against truck payload?
Yes. Tongue weight is supported by the tow vehicle and uses payload along with passengers, cargo and hitch hardware.
Should tongue weight be based on dry or loaded trailer weight?
Use loaded trailer weight. Cargo, water, batteries, propane and their placement can change actual tongue weight.
