The American company Beall Trailers is based in Portland, in the US state of Oregon, and builds tank trailers and semi-trailers for the American and Canadian markets.
When I was in California in March 2000, I not only had business at Bill Signs Trucking in San Diego, I also had to track down a tank trailer that would complement the American tractors in the Revell range very well.
And I found one at a haulage company in Los Angeles called Benito Tank Lines, which was then the largest tanker haulier in the United States. More pictures here: Beall Tank Trailer
