I am about to tow a 2900Kg (fully loaded) caravan and have had a pair of Airbag Man Airbags installed. Historically I towed with a Jeep Grand Cherokee and had a WDH to help with the load. However, that meant a very large and heavy tow-hitch. My question is now that the Y62 is a lot bigger and heavier tow vehicle do people still use the WDH? All towing will be on bitumen.
