Is your engine powerful enough to pull the trailer. Probably so. Is the payload spec on your truck matched to the vertical load of the BH3685RL? Probably not.
The empty rig pin weight spec is 2320. When loaded, what will the real weight be? Depends on what's in your rig. Ours is pretty fully optioned and our actual pin weight is almost 900# more than the spec.
Let's assume your actual pin weight will be 2700#. Next find the payload of your truck, which is probably available from Dodge or the Trailer Towing Guide. It varies by year, model, and configuration. Let's guess that yours is 2400. But subtract from your payload the weight of your hitch, tools and other stuff in the bed of the truck, bed liner, cover, passengers, and anything else that isn't in the empty truck weight. Let's guess your available payload is 1700#. You'd be 1000# overweight.
Does it matter? Will you bottom out your suspension every time you hit a bump? Will it cause excessive wear and mechanical failures over time? Will your truck handling and braking be affected? Will your tires be overloaded? How bad will it be?
Getting more info helps (which of course is why you're asking).
