We recently bought a 2021 Grand Design 310MKS. Empty weight is 10,495 and GVWR is 13,995. I am looking at 2016 Dodge 2500 crew cab with a 6.4 liter Hemi engine and a 3.73 gear ratio. The listed towing weight is 12,761. Is this enough truck for my rig or do I need to keep looking? If so, what should I look for?
