Looking for a 5th Wheel to double tow, need advice

On our 2014 factory ordered 27-5L, I was told by the local dealer that Northwood Mfg. would no longer be installing hitches for double tow. There previous offered two year warrantee is now only one year. The dealer said I could add a hitch but during the first year my warrantee would be void so I decided to wait and possibly add one this year or might downsize some toys as not getting younger! Northwood still make their own frames which is a big plus for strength.
