Just a thought... you may also want to consult with your insurance company.
I can't find it now, but I remember reading on an RV forum sometime last year about someone with a 5th wheel rig involved in a crash... and they were complaining that their insurance company was refusing to pay claims because they were using one of those type systems.
Again, I don't remember the exact wording in the post, but it was something along the lines that the insurance company said they had the right to reject the claim based on the fact that their policy stated the use of any modified and/or non-standard equipment to connect the RV & tow vehicle were grounds to make the policy null & void.
