Something about this just don't sound right. 2 blown bags on a 2013 isn't very long of a service life for the bags at all. And is the truck riding on the OL springs when towing causing a problem like ride, bouncing, etc? Reason for asking is as others have stated, thats what they are there for. I'm guessing bags aired up to high, improperly installed, or grossly overloaded (again just a guess). If a 2013 3500 dually with air bags isn't working out for you then I don't know what else would help except maybe a Freightliner MDT. Timbrens, sumo springs, or the like may work. But I cant see them being a better option than bags considering the weight your carrying and a great TV under it already.
