According to Mike King, in his Southern Coaches Survey ( 2019 ), it was considered that the ex-LCDR six-wheelers were some of the best for comfort so other vehicles were kit-bashed into electric units instead ................ mind you, I suspect other 'new' electric units were rebuilt from LCDR four-wheelers - retaining little, if anything, other than the door furniture !
