Can't help you with trails in Morris County. There is not much that is legal in NJ other than the pine barrens.

As for NJ dealers, I was always satisfied with O'Brien Nissan in Hawthorne NJ. They had a good service manager, Guy. The ownership just changed recently, so I can't say how good they still are on sales, but Guy is a service manager after the change and service still seems good.
