Pulled my 89 31ss with a chevy 1500ss one weekend and it was no fun. Now my 05 harley davidson f250 pulls and stops it great. We can do 85 on the interstate and can't even tell the boat is behind you. Depends on your bake system to. Mine aren't electric they are pressure driven. All In all the Denali will do but upglrade when you can for your safety and the other drivers on the road.

I pretty much killed my escalade pulling my prowler.Stepped up to a dodge 3500 diesel and you dont even know the boats back there
