Bedford Lorries, you used to see them everywhere

Just looking at this thread . I remember growing up in 70/80s and bedfords were everyehere . I lived near to the roadline depot Iin Leicester and they had loads of TKs , Other local hauliers had plenty TKs and KMs , some had TMs . I used to spend a lot of time in trucks with my dad and every other rigid truck on the road was a TK or TL . Just wanted to know why they went so soon . I know all the brit stuff has gone , but most of the big names lasted a lot longer . I know AWD did some strange multi-drive stuff .
