We have a 2010 Bighorn 3670. Had a 2002 2500 Chevy Silverado 4x4 when we bought fifth wheel. Duramax and all has gone very well pulling 5th wheel. It did have the long bed, butt when I did research a short bed would also work. Had airbags installed. New dilemma. Just purchased a 2015 Silverado 4X4, 2500 diesel w/ crew cab shortbed. This vehcle is also with offroad package. Question...anyone have this type set up? Stiffer suspension and was told to use before getting air bags.Also wondering about hook up as this vehicle seems a bit taller. Thanks for any info
