Traila — Mexican / US-border trailer slang
Traila, tráila, Mexican trailer, Mexican RV slang, border RV México, casa rodante México
Traila is the colloquial Spanish loanword for "trailer" used in Mexico and the US border zone. It can refer to a simple utility trailer or to a towed or self-propelled casa rodante. Common in rural Mexican speech.
Northern Mexico (Sonora, Chihuahua, Baja California) hosts thousands of US and Canadian snowbirds wintering in their "trailas" at RV parks — especially Puerto Peñasco / Rocky Point, San Felipe, and the Baja peninsula. The term coexists with motorhome, casa móvil, and casa rodante. Official paperwork uses remolque or vehículo recreativo.
