We doubt we would modify my wife's 2009 E320 CDI to tow since we are using my 2007 ML320 CDI to tow our 2015 23D International Serenity that weighs 6,068 pounds camping ready after all of our modifications. The ML is about broken at 151,000+ miles. We use a HEnsleyArrow hitch between the ML and the trailer.
