The 'drag bars' are on there for a reason. moving the bars or adding wheel 'drag bars' will not solve the problem. After a while you will destroy the wheel 'drag bars' (been there and done that). If this is happening (dragging) all the time...... you need a higher camper, for you will tear something up much more worse, 'down the road'. ie, bend the frame or drag something important off on the underside to the unit.
