Weight dist/sway system you don’t need to install every time

I towed a 22' travel trailer with an expedition and even with a sway bar I got alot of sway when trucks went by. I switched to a Chevy 2500HD, no WDH or sway bars and had no problems at all and the tongue weight was barely noticable compared with the expedition. Since then I moved to a 5th wheel and there is no comparison as to which one is easier to hook up. The 5er is way easier to hook up and almost hooks itself up when backing. Also, no WDH or sway bars to fiddle with.
