I bought a 2004 Titan KC in June of 2004. I told the salesman that I was going to get a5th wheel trailer. He said I should have no problem towing. I found out in Dec that Nissan does not recommend towing a 5th wheel or gooseneck trailer and that doing so would void my warranty. I have talked to several different people in Nissan customer service and warranty departments. No one can give me areason why I can not tow a 5th wheel. Has anyone else been told this or have any information?
