I'm about ready to pull the trigger on a new TDI but am concerned about it's towing abilities. I'm pulling a 20'box trailer with race car, tools, pit bike,,etc. Haven't scaled it but I'm thinking it's around6k - 7k lbs. fully loaded. The Touregs torque & 7700 lb rating seems ok but I've read somewhere in the forum that the max hitch weight is 308lbs. If I use the 10-15% rule of thumb for distribution, it seems the Toureg will not work. Also, a buddy of mine who has a Cayenne, said he can't use a weight distribution hitch due to suspension & on-board computer. Would this apply to the VW? I want the car but may have to go with my original choice being the Gas Tundra or F250 diesel. Thanks in advance.:dunno
