What is a common buying mistake?
Buying from a headline rating or feature list without verifying coupler/hitch fit, certification, physical fit and real-world installation requirements.
When is a premium option worth it?
When the extra cost materially improves lock construction, safety, durability, reliability, support or long-term usability.
What should I verify before ordering?

Why are there five recommendations?
Five distinct buyer roles create a useful shortlist without turning the article into a repetitive catalog.
