Mushey Off Road tires and a Higher Center of gravity can be really dangerous with a Big Heavey 5th Wheel trailer. However a Raised Dually set up to clear 22.5" Big Truck Wheels and Tires is a different story.
I have seen at least 3 overturned raised Crew Cab 4X4s pulling Toy Box's (One a Dually) on Interstate 15 going north toward Vegas. I like raised trucks but If I had a 5th Wheel Toy Box or trailer I would not want a raised truck.
