The World's Largest Truckstops


WALCOTT, IA – The Iowa 80 Trucking Museum will host a 100th Birthday Party for its 1923 Mack AB on Friday, July 14th at 2:30 pm. The event will coincide with this year’s Walcott Truckers Jamboree, July 13-15. The public is welcome to attend the celebration and enjoy a piece of cake to celebrate 100 years of trucking.

The Mack AB model was Mack’s first standardized, high volume model series. This model was first introduced in 1914 and replaced the Mack Jr. line. The first AB models had chain drive or worm drive but were replaced in 1920 with a dual reduction drive. This medium duty truck’s simple, classic styling made it very popular. Mack Abs were produced through 1937, with over 55,000 units produced.

According to the Iowa 80 Trucking Museum Curator, Dave Meier, this 1923 Mack AB was originally purchased by Headley’s Express & Storage Company of Chester, PA. It was delivered to Chester, PA by the Mack Philadelphia branch on June 14th, 1926. Bill Moon, Iowa 80 Truckstop founder, purchased this truck 55 years later in January of 1981. Moon was known to be fond of Mack trucks, which is evident by the historic photos of Mack wreckers that had been used on the Truckstop property in the 80’s and the number of Mack trucks in the antique truck collection that he started. This Mack AB has been displayed at nearly every Walcott Truckers Jamboree since its purchase and was restored in 2004 to reflect the green and black color scheme that it hosts today. This truck is currently on display at the Iowa 80 Trucking Museum in Walcott, Iowa.

Photos of this truck and founder, Bill Moon prior to restoration are available upon request.
