I bought a Nose Cone back in '01, factory installed by Nose cone themselves. The price then was just under 700$. My fuel mileage went from an average of 5.6 to 6.2, but the best part was the added control in cross winds, no fighting the steering wheel. I'm not sure if the Cone is also the reason my trailer tires seem to wear less, a lot less. I've got over 260k miles on my trailer tires and still have over 50% of the tread left.
I've also pulled other trailers w/o the Cone, and the difference is night and day in handling and fuel mileage. I've had zero problems with my Nose Cone in 8 years. I have lent my trailer to other o/o for a load or two and they love pulling it, even tho it is on the heavy side, being a Great Dane, it pulls much better then any make of trailer that doesn't have the Cone.
