Abstract: A utility package for installation in the bed of a pickup truck includes a frame (10) having a relatively narrow, lower vertical section (12) of a width W1 narrower than the interior spacing between the sides of the pickup truck bed while substantially spanning the entire interior distance between such sides and a relatively wide, upper horizontal section (14) of a width greater than the interior spacing between the sides and no greater than about the distance between the exteriors of the sides and adapted to be supported on the tops of the sides. An elongated pressure vessel (26) is located within the vertical section (12) and a pair of upright housing sections (64,68) are mounted on the horizontal section (14) oppositely of the vertical section (12). The housing section (64,68) have access openings (78) at respective ends (16,18) of the horizontal section (14).
