travel trailer / RV tongue weight calculator

travel trailer / RV: the 10–15% rule

A travel trailer / RV should carry 10–15% of the gross trailer weight as tongue weight, with about 12.5% as a practical target. Enter your loaded weight above and the calculator returns the exact range in pounds (or kilograms).

Loading a travel trailer / RV to hit the target

Where you place the load is what actually sets tongue weight — the percentage is just the goal. To keep it in range:

• Load about 60% of the cargo weight ahead of the trailer axle(s) and 40% behind.
• Put heavy items low and centered near the axle; secure everything so it can’t shift on the road.
• Full fresh-water and propane tanks up front raise tongue weight; a loaded rear cargo hatch lowers it.
• Re-check tongue weight whenever you substantially change how the trailer is packed.

Typical setup

Half-ton pickups and full-size SUVs; single- and double-axle travel trailers and campers.

Verify by weighing

The number above is an estimate from the standard percentage. Your real tongue weight depends on exactly how this travel trailer / RV is packed, so once you're loaded, measure it. Also check whether your rig calls for a weight distribution hitch, and make sure your hitch class and ball mount are right for the load.
