This is a slightly different question than what the "how do you transport your dogs" thread may cover so I thought I would make a new thread. When I was a kid, I remember our dog just jumping up into the back of my dad's truck but these trucks are so high, that is a big jump for even a large dog. Do you have any ramp or step recommendation that works well to get them up in the bed and doesn't take up a lot of room when stored?
