When I got to my first working unit in the army we had the selection of Bedford MJs - old design but late production - and AEC Militant Mk 1s. Built in the early 50s, 6 wheel drive, 6 crash gears, no power anything and a top speed of 32 mph. This was in 1988. The AECs were replaced by 6 wheel drive Bedford TMs which were a revelation. Both types of Bedford are still in service and it always amuses me to see civilian models restored as classics.
Some of the Bedfords were replaced in the early 90s by Leyland DAFs , which were much easier to drive but nowhere near as tough. Funnily enough, the DAFs are now being sold off and the Bedfords they were meant to replace are still in service. Some units still had a few Bedford RLs, even as the DAFs were coming in.
