Was Leyland then daf not sure what the current GP truck is?
Oh I'm going back to the 70s for the RLs. Missed a chance to drive one in a surveying company in uses to work for. Reputedly 4mpg on road, 2.mpg off road (iirc)
I dread to think what the daily fuel bill was at that company thinking back there were...
Bedford RL converted to a control truck .
Diamond T drill rig, capable.of drilling to 100ft
A couple LRs converted to small.drill rigs for 10ft drilling
Probably 6 LRs, 3 5 ltr engined for cable carrying and general transport
A Fordson Major (iirc) tractor for towing a water bowser
One explosive carrying LR.
We just uses to fill up every single day, must have been astronomical.
