I agree 110% on Tn Trailers.. They built one for my 20' Sprint Dual Console and I love it! The quality is second to none.. Wheel bearings are maint free and warrantied for 100,000 miles. All lights are LED and they will even paint it what ever color you want. They painted mine to match my truck. You might also find you can get a single axle, thats what I have and its great and the tires will last a lot longer too.. I know my Sprint has to weigh more than your Nitro as Sprints are HEAVY!! Check them out and I bet you will go with them.
