I'm not sure if it would or not. With the unit mounted in the back door, behind the axle, it's positioned to receive the maximum amount of movement up and down, since the further from the center of rotation, the larger the distance it moves. Think of a record, the outside edge travels much further than the center with every revolution. If the A/C was mounted closer to the center point of rotation, it should move less. That's taking into account the travel when the front wheels are higher and lower than the back. When the wheels are all moving up and down together with little rotation it's a different story. On my van, I would guess that high speed washboard will kill the A/C no matter where it's located, but others with softer suspension and lower speeds may have different results. Stick to paved roads and it should last many years.
