So, I've come to notice that not every tractor has a fifth wheel puller, and many drivers take them and hide them away in their lockers......why is this the case? Shouldn't they just be in every tractor, so no matter who uses the truck, there's always a puller in it? I giess it's similar to handcarts in delivery, but I REALLY hate not having a puller and having to reach in under the trailer to uncouple
