Have a 2014 Ram 1500, 5.7 Hemi. Looking for first trailer. Manual says max towing is 10,400lbs. Looking at Cougar 28ft trailer @ dry weight of 6400 and a Cougar 5th wheel, 28ft at 7000 dry. It looks like the "numbers" work, but is it realistic ? Truck GVWR is 6900 GCWR is 15,650
You will probably be over on your payload capacity. Check your door sticker for the number. It will say max weight of people and cargo should not exceed X. If not, subtract your GVW from the weight of the vehicle and that's your number. Most people figure 20% pin weight for a 5th wheel and your trailer should have a dry tongue weight number. When you hitch these two trailers (tongue weight or 5th wheel pin weight) to your truck all that weight goes on the truck and is included in the truck payload capacity. Hope this helps
