Yes the companion does move too much in my opinion. I just went to the local steel yard and bought a 1 1/2 x 3/4 piece of barstock to add to the rear turnover ball crossmember so it will be stiffer. The engineer I have been dealing with told me about someone he was working with about a year ago...must have been you. Anyway it seems, from reading a few of the lasts posts here, that withthe companion uprights in the most rearward and highest position is what is giving the companion enough leverage to flex the turnover ball hitch and even this "prototype" version I have is just not stiff enough. I think if two more holes were drilled in the rear most skid portions (and through the bed) of the companion and bolted to an additional crossmember, it would alleviate the problem. But that would defeat the purpose of having an easily removeable hitch and a clean bed. I have mine setup so I can turn sharper because I camp/hunt and am often way out in the boonies. I may need to try and "jockey" the toyhauler to get it just right. I think I am headed toward replacing the companion with a superglide so I don't hit the cab but I am not sure at this point. I have to figure it out soon because I am about to go on a 3000 mile round trip and absolutely will not settle for a hitch "jerking" me around....lol. I am still waiting to hear from the engineer as of my last update to him.
