Anyone seen one of these yet? I was watching Trick my Truck tonight and they put one on an old Mack Truck that they restored. I was curious if anyone has used one or if this thing really works better than putting grease on the 5th wheel.

I thought it was pretty cool. It was made by Alcoa and Holland I think. Looked pretty cool.

they work well, the problem is if you haul different trailers, you will end up covering it with grease anyway. However, if you pull the same trailer all the time, it's great
