I have a 2004 All American Sport 5'ver (toy hauler) that is pitched to high in the front when hitched to my truck. I have the pin box and my fifth wheel set to provide the lowest possible trailer height without risk of damage to truck bed rails. Is it possible to lift the suspension on my trailer to make it more level when being towed? The trailer has tandem 6000# axles with Al-Ko Rubber Independent Suspension. My truck has a 2" suspension lift in front and a 1"in the rear along with Air Lift Super Duty's. Thanks All.
