Ok? Just bought a 2006 35 ft fifth wheel with the gooseneck adapter and already have the B&M gooseneck hitch in the truck. I?ve read all of the responses about it ?could? void your warranty (which I don?t have ) or "could" cause damage. I?ve called several dealerships and get a mix of responses. (Usually feel most likely it?s based on if they are trying to sell me a new hitch!) Out of all the research I?ve only found one person that spoke about damage but stated it may have been self induced. So? how many of you have actually had a problem or seen a problem yourself, in which was caused by using the fifth wheel to gooseneck adapter? Thanks for the feedback. I?m not trying to do the wrong thing or to be taking chances on the highways with others at stake, but just can?t find any real documented issues that would convince me to go and spend all the extra money when I really like the GN
