I decided the 3.0 diesel was not a safe bet to haul my trailers, so I have purchased a 2020 2500 HD with the 6.6 gas engine. It won't get much better mileage than my 2005 2500 HD 6.0 gas, but I won't have to worry about towing.
topgear1224: tongue weight conventional = 10%; gooseneck = 15%. But the diesel looses 3,300 lbs of trailer weight on the gooseneck? Why? I always thought you could haul more on a gooseneck than bumper pull? The weight limits seem reversed to me.
Is anyone out there using their 3.0 diesel to pull a gooseneck trailer? I intend to use it to pull a GN 3 horse trailer at 7500-8000 lbs. Does it hold level or will it need air bags or air shocks?
