How We Research These Guides

Every specification on this site comes from the manufacturer's own page for that product, and the link to it sits next to the figure. Every regulatory claim links to the regulation. Where a manufacturer does not publish a number at a stable address, the page says so rather than estimating - which is why some product entries carry a specification table and others carry a sentence explaining why they do not.

What we will not cite as the source of a fact: a forum post, a Reddit thread, an AI-generated summary, or another affiliate site. Those are not sources; they are places where sourced and unsourced claims look identical.

• We have not towed these products. No instrumented stops, no measured sway onset, no fill times, no gauge deviations. No page here is written in the first person about products we have supposedly used, because there is no such experience to report.
• We publish no numeric scores. A score out of ten implies a measurement. Where a comparison table needs a verdict column, it carries a short qualitative read instead.
• We publish no star ratings or review counts. We hold no licensed ratings data, and there is no Amazon Creators API credential for this site, so any rating here would be invented.
• We publish no prices. There is no live price feed. A stale price is worse than none, so every buy link simply goes to Amazon, where the current price is shown.

Four questions, applied in order, and none of them is a score.

1. 1Does the mechanism address the reader's actual problem? A friction bar and a weight distribution hitch solve different things. Most bad purchases in this category are a correct product bought for the wrong symptom, so the matching comes first.
2. 2Does the manufacturer publish what it claims? A maker that publishes a rated range, a torque figure and a capacity chart is one whose claims can be checked. One that publishes marketing copy and a photograph is not.
3. 3What is the failure mode? Every product here has a stated "skip it if" line, and it is written from the design's genuine weakness rather than invented to look balanced.
4. 4Is it currently sold, in a form a reader can actually buy? Superseded part numbers are flagged where the manufacturer lists them as such.

Most trailer sway is a loading problem, and loading is free to change. Most trailer lighting faults are a bad ground, and cleaning a ground bolt costs nothing. A site funded by affiliate commission has an obvious incentive to skip past that and get to the hardware - so we have made the opposite the structure of the pages. If the honest answer is that you need nothing, the page says so before it says anything else.

If a figure here is wrong, or you can source something better than we did, tell us. Corrections are read before anything else in the inbox, and a corrected page carries an updated modification date.
