Abstract: An easy to install pull out cargo-carrying tray frame device includes a stationary frame to which is attached a wedgeable attachment member that can be employed to secure the stationary frame to a cargo area of a vehicle or trailer. The device can be part of an extendible drawer or tray device, and can be especially adaptable for a pickup truck. An extension can extend laterally from the stationary frame, to which the wedgeable attachment member can be attached, so that the stationary frame can be secured to the cargo area, and the wedgeable attachment member can be vertically oriented and extensible. The lateral extension member can have a sliding-interlocking relationship with an engagement member to which the wedgeable attachment member can be adjustably attached. Alternatively, the wedgeable attachment member can extend in a horizontal direction to engage and be wedged between side walls of the vehicle or trailer cargo area. A plurality of wedgeable attachment members can be present.
