Our roving reporter Gerry Burr visits two of his favourite commercial vehicle rallies, to seek out the rarest, the biggest and the best, in the world of commercial vehicles.

First stop is The Truckfest Vintage Commercial Section at Shepton Mallet Showground, followed by a visit to Yeovil Festival Of Transport Parade Ring. We see everything from small delivery vans to the mighty Scammel, articulated lorries, fire engines, buses, military vehicles and even a Ford Model T pick-up truck. So sit back and enjoy these Classic Commercial Vehicles.
