Hej Per, In the 1960`s Leyland and some other English makers advised that double drive would be needed for over 30 tons totalweight ,with regard to traction issues on snow and ice ect , even though it was always pointed out that Sweden worked OK with single drive at weights of around 50 /60 ton !, but as can be seen in the images some in England used double drive for 32 ton total weight ,even though the legal payload was reduced and fuel economy was not so good , most of Leylands exports to Iceland ,Norway ,Denmark ,Belgium ,Poland and East Germany ect used 4x2 single drive as in England , when the UK total weights were raised to 38 tonnes in 1983 only Foden thought tandem drive was needed , MVH Alan.
