This was my choice for use with the TrailAir hitch. Upgraded just today.
Got concerned since my Hidden Hitch 18K was at max capacity. It had been purchased for use with my previous coach.
They are currently selling at reduced price in an effort to get some out on the road. 7 year warranty isn't too shabby either. I put the etrailer link up since they give some really good pics of it. Another site had it for $479.
