i have a ragn toy hauler converted to a gooseneck and all my problems were gone i got better handling and more storage. the company that did it is in san diego ca and i highly recommend them for the modification. it cost about $5000 with a B@W turn over ball hitch included. they said they can also turn it into a 5er if needed they have acyually posted pics of the retrofit on toy hauler mag forums (cant download my own pics yet) if you want another option for bent ww frames check out the post (profiactic fix is a waste of time on the forum or check out the web site www.t2ktrailers.com
