So I will be towing my 14' cargo trailer from Canada to Baja and back. Loaded with 5 bikes and gear, I'm going to be right around 5000lbs including trailer weight. I have deaver plus 3's and fox 2.5 air bumps on SVC adjustable bump hangers. I'm wondering if I should be putting a weight distributing hitch on as well. Anyone with similar truck & towing setups out there? I've been towing trailers for over 20 years for work and pleasure, just not much with this truck so far.
