Manual slide 5th wheel

Aw, don't feel bad for asking, Laddie, it's why we're here. A sliding 5th wheel of any kind is kind of a thing of the past. As mentioned, big fleets generally haul the same trailers, and no need to slide. It's a greasy, dirty PITA anyway, and air slide rarely works, as it's not used much. Used to be, a slide was needed to get more weight on the steer, but I don't think that's an issue with todays trucks. What a fixed 5th wheel DOES require, is careful loading with heavy loads, and a rear suspension air gauge is paramount.
