I remember seeing an advertisement a few years back for a double deck trailer. It (supposedly) allowed you to put a boat w/trailer on the upper deck, and a toad on the lower. I have researched everything I can think of on the internet, and have not been able to locate any information. I presently tow a pair of waverunners behind my 5er, but we are seriously considering trading in for a class A. Any information would be greatly appreciated
