Truck Camper Struts - Good? Useless?

I've never experienced any of the porpoising described in the Truck Camper magazine article, and I don't know anyone who felt that they needs the struts. The newer trucks are heavier duty than ghe ones from the 70's, so what was needed then may not be necessary now. I'd try the rig without them for now. If you have a lot of porpoising problems, you can always add them later for the same cost. If you find that you don't need them, you've saved a lot of money. I don't see any reason to add gadgets or fix things until I know that I need to.
