In 1974 four local men with ties to the dairy industry started a business repairing stainless steel milk tankers. Shortly after 4 Guys was established, the company solicited new investors and shifted to building fire apparatus.
At first, the company built elliptical tankers based on their original milk tanker design. Soon, satisfied 4 Guys tanker owners started coming back, asking for pumpers and rescue trucks.
Today, 4 Guys produces nearly twice as many pumpers as tankers. The progression has been gradual, but as customer confidence has increased, 4 Guys has grown to meet the demand.
