what kind of car was in the long long trailer
The Long, Long Trailer The trailer used in the film is the 1953 36-foot Redman "New Moon" model, which sold for $5,345 (equal to $48,889 today) at the time. The new car used to tow the trailer is a 1953 Mercury Monterey convertible with a 125 HP flathead V8 engine.
Semi-trailer truck The cargo trailer usually has tandem axles at the rear, each of which has dual wheels, or eight tires on the trailer, four per axle. In the US it is common to refer to the number of wheel hubs, rather than the number of tires; an axle can have either single or dual tires with no legal difference.[5][6] The combination of eight tires on the trailer and ten tires on the tractor is what led to the moniker eighteen wheeler, although this term is considered by some truckers to be a misnomer (the term "eighteen-wheeler" is a nickname for a five-axle over-the-road combination). Many trailers are equipped with movable tandem axles to allow adjusting the weight distribution.
