The milestone, which was reached following Parker's insistence on DAF trucks at 7.5 and 12 tonnes since 2001, comes after a 20 year history with the truck manufacturer – originally building bodies on DAF 45 Series chassis.
"The DAF chassis is simply the best on the market," insists Parker.
"We started building on DAF used chassis over 20 years ago, and with the introduction of the DAF LF range we moved to 100% DAF," he continues.
"Despite the fact we're acquiring more and more new LFs today, the two-year-old used DAF LFs are as good as new."
For Parker, DAF's build quality is good and provides a "textbook platform" on which to build its bespoke horseboxes. In fact, his company has employed ex-Leyland Truck employees for their skill-sets with the chassis.
As for horse-owner Bill Christie in Ayrshire, he says: "My daughter Jeni, and I absolutely love our new DAF. Iit's like driving a 28ft long car."
