Howdy folks. Just bought my 2016 Silverado 3500HD DRW long bed for my new 5th wheel trailer. Old truck was a 2500HD 6.0 gasser, but my travel trailer was only 8800lbs, so it was fine. Currently trading in for a 14,000lbs DRY, 16,400lbs 5th wheel, so needed the pulling upgrade. On here for research and general knowledge from the long time Duramax folks here. Live in Virginia Beach and am in the Military. That's me I guess......
