My truck already has a gooseneck hitch installed and the saleman at the dealership said all i needed was a 5th wheel adapter for the gooseneck and i would be fine. the owners manual states that you should not use the 5th wheel adapter and it will void the warranty. just bought the 2012 heartland bighorn not trying damage it or void the warranty. any suggestions? ps: i havent picked up the BH from the dealer yet.
