As a general rule.

On a vented cooling system, the headder tank should be at the highest point of the system.

You don't want to be risking poor circulation or possible air locks

How would you fill it up though George? as soon as you take the cap off the water will escape and the air buffer would collect in the radiator rather than the header tank.

Yes, afraid it does need to be at the highest point. Attach it to one of the front top rails, should be fine. It's quite easy to modify the Sierra one to do this.
