Translation guide
The English word 'trailer' has several distinct meanings. This guide covers the most common ones for learners: a vehicle pulled by another, a preview of a movie or show, and a mobile home. Each meaning uses different Japanese words.
A wheeled container or platform towed behind a vehicle for transporting goods, equipment, or animals.
The most common and general term for any kind of trailer, from small utility trailers to large semi-trailers. A loanword from English.

I hook up a trailer to the back of the car and pull it.

Literally 'towing vehicle', but can refer to the trailer itself in technical contexts. More formal and less common in everyday speech.

Also commonly used for movie/game trailers, especially in casual or online contexts. Often interchangeable with 予告編.
Short for 'promotional video'. Often used for music videos, anime, or game trailers. More common in entertainment industry jargon.

Specifically a camping trailer or caravan. Often shortened to just トレーラー in context.
