Honestly I did not have a good experience with the trail tank on my Nytro. It fit, but it took a lot of work to get it lined up. I had to drill extra holes for the hood screws, and it left big gaps on either side where the plastics no longer lined up correctly. You also lose your fuel gauge, so you always have to open the tank and guess at how much you have. In addition to that if I filled up too far it would syphon off the top of the fuel due to the vent location.
Unless the design changed, the fit and finish was very poor on the one I had. I needed it for the boondocker setup I had, but otherwise I would have just ran the stock tank and hauled an extra 2 gallons of fuel on the back.
After reading Chris's thread, I must have had a first generation trail tank. I know the run that I had was made with a scoop in the bottom to clear a front mount turbo. My kit was a boondocker, which has been discontinued for a few years for good reason.
Looks like the issues got sorted out though, happy trails!
