I started driving trucks in the mid 70’s. Under 3ton u.l.w. and all ok on a car licence as a teenager. Drive TKs a few times but normally a D Series Ford.
The workshop hack was a “genuine” Class 3 D Series (ten stud wheels etc) with the bed and chassis cut off just behind the back axle, to bring the empty weight down, so we non-HGV drovers could drive it. With a load on it was a beast to steer.
Had a 1966 Commer before the Ford and a few times in a 1958 Albion. The Albion was deafening, and not just because of the tunes I was playing on the gearbox!
From what memories I have of then, and speaking from the vast experience of being a teenager(!) the TK stacked up well against the Fords, and was clearly streets ahead of the older trucks.
If I remember correctly the TKs had proper air brakes whereas some others of similar weight has vacuum brakes or air-over-hydraulic systems.
