The bed cover rests on a machined raised peripheral rim on the upper surface, and is additionally supported on resilient non-metallic material deposited on pads interspersed on the upper surface which are machined to a level below the raised peripheral rim to accommodate the non-metallic material between the bed cover and the pads. The cover is firmly fixed to the top portion of the bed casting by a skirt portion of the prepainted bed cover which extends about the periphery of the top portion, and is swedged beneath the top portion of the bed casting to form a unitary assembly therewith.
