EZ Classic is often referred to as the "tube mount" in that it has two receiver tubes that the tubular Lift Frame slides into, secured with pins. The Lift Frame with the pump and lights can be removed in the off season ,and it was encouraged that it be removed in the off season. Like the EZ Custom, the Mounting Cartons were vehicle specific. so again, you could not modify a Ford Mounting Carton to fit a Dodge, or a Jeep Wrangler Mounting Carton to fit a Jeep Cherokee, not easily anyway. The Lift Frame however was universal in that there was one Lift Frame for all Fullsize trucks, and one for all downsized trucks (think Ford Ranger, Chevrolet S-10, Jeep Cherokee), and finally a third Lift Frame that only fit the Jeep Wrangler. It came out in 1991, and was discintnued as a complete new system in 2009.
