Not a deal breaker, but the Troll carriages have a tendency to fracture the welds at the boss where that the 1/2 rod attaches to. If so, it's an easy weld. I can fix them for you if need be. If the Trolls are slow going up and down, good chance the roll pin that holds the 2 bars together, in the coil sleeve, is working it's way out. (Yup, that long rod is 2 put together). Either needs to be taped back in, or eliminate the roll pin, weld and finish it. That's what I did on mine.
Great Machine, you will enjoy the hell out of it.
Good luck!!
