Too little and too much are both failures
Tongue weight is the downward force the trailer coupler puts on the hitch. Too little, and the trailer can sway. Too much, and the tow vehicle's rear squats, the headlights aim high, and the front tires steer poorly. Debris makes this worse because a few pavers or a stump moved forward or back change the tongue a lot. Put heavier pieces slightly ahead of the trailer axle, not stacked behind the axle and not piled against the trailer nose. The goal is a modest, steady push on the hitch, inside the rating of the hitch, the ball, and the tow vehicle. Those ratings are on labels and in the manuals. This is not a guess to settle after you are on the highway. A bathroom scale method or a tongue scale, if you have one and use it the way the scale describes, beats a feeling you got from a boat trip years ago.
The driveway roll is the test
Hook up, cross the safety chains the way the hitch article you already know requires, and roll slowly in a straight line and then through a gentle turn. If the trailer wags, you are light on the tongue or loose in the load. Stop and move cargo forward a little, or add a strapped heavy piece ahead of the axle. If the tow vehicle's rear is down on the stops and the steering feels vague, you are heavy. Move cargo back toward the axle, not behind it, or take cargo off. Do not fix a heavy tongue by putting people in the cargo area. Do not fix a light tongue by standing on the hitch. Reload. A stump behind the axle is a classic light-tongue, heavy-sway setup. A stump jammed into the nose of a small trailer can be the opposite problem.
Straps keep the tongue you just set
Tongue weight changes if the load slides. Strap the debris so the balance you just set is the balance you will still have at the site. A sliding stump moves the tongue on the way. At the bay, unload without climbing on the trailer tongue. When the trailer is suddenly empty, the tongue can jump. Lower the jack before you take the last heavy piece out if the coupler is still on the ball, so the hitch is not the thing catching a flying trailer. If you never got the driveway test to feel calm, do not start the trip. Take a smaller load.
Before you go
- Compare the hitch, ball, and vehicle ratings before you load the trailer.
- Place heavy debris slightly ahead of the trailer axle, then strap it so it cannot slide.
- Roll in the driveway and move cargo if the trailer wags or the tow vehicle squats on the stops.
- If you cannot get a calm roll, remove weight instead of hoping the road is straight.

Questions people ask
Can I add a sandbag on the tongue as a permanent fix?
A small, strapped adjustment can help a light tongue, and it still counts as weight on the hitch. If you need a huge bag, the cargo is in the wrong place or the trailer is overloaded.
Does a weight-distributing hitch replace tongue limits?
No. Use it only if the vehicle and hitch maker allow it, and stay inside the ratings. It does not make an overloaded trailer legal.
