I did lots of research and looking at comments by users. There are few people who have not been happy with the Blue Ox, but the few that did not like them seemed to have longer trailers. The tech told me they have had issues with toy haulers and also some of the longer trailers, he suggested not to put a Blue Ox on any trailer over 28 feet long.
I don't necessary agree with that, I think it has to do with your particular truck and trailer and every one will be different depending on weights, loading etc.
There are many users who love them and have no issues. I was just unlucky to have a setup that did not work.
I am very happy that my dealer changed out my set up at no cost to me and was willing to work with me a year later on my set up.
