As I told you, you don't need to ask for the 4100 tractor. Fact is when I bought mine, I'm not sure there even was a 4100. Either way, the only suitcase weights they had at this dealer was all the same size. But I do remember, they were not in the parts part. They were over in another building. But either way I think you got a raw deal, some of these places think they are above everyone else.
