 All of the vehicles had 2-axles, with an entrance in the centre of the vehicle.A variety of configurations was available and Hull Corporation trialled a Roe bodied Sunbeam in February 1953, which had a separate entrance and exit, and twin staircases.This reduced the seating capacity to 54, but the design, which was specified by the Transport Manager Mr G H Pulfrey, was well-received, and an order for a further 15 such vehicles was placed in April 1953.
