Seeing as how you're in Knoxville, my advice is for you to make the short drive to Harriman and visit Robbie and the folks down at Bunch Marine. Don't know anything about a Nitro or any local Nitro dealer. I can tell you that while I do like my Triton a lot, I own that brand primarily because of the service and support I have received from Bunch. Not a better outfit to do business with anywhere, IMO. Good luck whichever way you go.
