Lets look at it this way: You have a Combined Gross of 13,800 you hook up an RV at your rated capacity of 9,600, now subtract that 9,600 from your GCWR and leaves you 4200 for your truck, cargo, 5th wheel hitch, and passenger. My bet your truck weighs more than the remaining 4200 Lbs. Plus to add to the confusion, those 8000 Lb Dry weights are for a base model before any options, so they actual out the factory door will usually be higher. My last two fivers left the factory better than a 1000 Lbs above brochure dry weights.
