Abstract
Abstract An improved engine generator set, especially adapted for a recreational vehicle or the like, includes a mounting tray dimensioned to be received through a recess in the floor board of the vehicle for mounting to the vehicle frame members. The mounting tray supports an engine whose drive shaft extends vertically downwardly through the mounting tray for mating with the shaft of a generator which is positioned directly underneath the engine so as to extend beneath the vehicle. In this way the overall floor space occupied by the generator set is reduced.
