rjok,
Is there really a question??? If there were some "substantial" price difference in favor of the Trekker, or a family member who sold them to whom you had allegiance, then I suppose the Trekker may seem a more appealing option. But, given your findings, I would suggest strongly that the John Deere machine would be your better choice. The reasons are plentiful, but the main one has already been cited: the reputation and support these vehicles have through John Deere is immense. They also really are pretty nice machines. I am sure the Trekker is fine also--and Land Pride has a solid reputation in the attachment venue--but for the same $$$$?? Although the XUV's are not perfect, and I personally am not particularly enamoured with the gasoline XUV's, I still think it would be your (much) better option in this case. It is a tough, pretty well-designed UTV with strong company backing.
