Quick picks
- Best overall: an integrated WD hitch with built-in friction or 4-point sway control — one unit, fewer parts to forget.
- Best for big trailers: a high-capacity head matched to your tongue weight, with strong dual-cam sway control.
- Best value: a round-bar WD kit with an add-on friction sway bar — proven and affordable.
Matching it to your trailer
| Step | What to check | Why |
|---|---|---|
| Find your tongue weight | ~10–15% of loaded trailer weight | The hitch must be rated for it — loaded, not dry |
| Pick the right bar rating | Tongue weight in the middle of the range | Bars too stiff or too soft both ride badly |
| Weigh loaded, with gear | Include water, propane, cargo | Dry weight badly understates reality |
The most common mistake is buying a hitch rated for the trailer's dry weight. Load the rig the way you actually camp — full fresh tank, propane, bikes, the works — find the real tongue weight, and choose a bar rating that puts you in the middle of its range. A hitch that's overrated rides as harshly as one that's underrated.
The reviews
Integrated WD Hitch with Built-In Sway Control
Sway control is built into the head instead of bolted on, so there's no separate bar to attach (or forget) at every hookup. Levels the load, resists sway from both directions, and is quieter than friction-only setups. The setup most experienced towers settle on.
Pros
- Integrated sway — fewer parts
- Strong two-direction control
- Fast hookup once dialed in
Cons
- Costs more
- Heavier head to handle
High-Capacity Head + Dual-Cam Sway
For heavy travel trailers, a high-capacity head with dual-cam sway control gives the most positive, planted feel — the cams actively resist sway rather than just adding friction. Dial-in takes patience, but the result is rock-steady at highway speed.
Pros
- Best stability for heavy rigs
- Active sway resistance
Cons
- More setup to tune
- Premium price
Round-Bar WD Kit + Friction Sway Bar
The proven, affordable classic: a round-bar weight-distribution kit with an add-on friction sway bar. It takes a moment longer to hook up and the sway control is one-direction friction, but for mid-size trailers it tows level and stable for a lot less money.
Pros
- Affordable and proven
- Easy to service
Cons
- Add-on bar to attach each time
- Friction sway is less refined
How to choose
1. Rate it to loaded tongue weight
Weigh the trailer the way you camp and aim for the middle of the bar's range. Dry-weight ratings will mislead you.
2. Don't skip sway control
Weight distribution levels the load; sway control keeps it straight. On a tall travel trailer you want both — integrated is the cleanest.
3. Set it up level
Measure the truck's front fender height before and after hookup; adjust the bars until the front returns close to its unloaded height. That's the whole point.
4. Re-check after the first trip
Bars settle and chains stretch a touch. Re-verify level and torque after your first real tow.
