Well I will post it again......"keep working on understanding the weight issue and when you do understand make the call. Let me use my numbers as a example.
The truck in my signature has a GVW of 13,000lbs and pay load capacity of 4268lbs and a GCWR of 23,500lbs (the total the truck and Rv can weigh)
The payload is the weight that we can carry IN THE TRUCK The truck ready to tow, full fuel and everything on board that we normally carry to tow is 9,000 .
now to get the actual payload we must subtract the the weight of the truck 9,000lbs from the GVW of 13,000lbs leaving 4,000lbs as the actual payload capacity not 4268 listed on the door sticker. That means that we have 4,000lbs left for my pin weight since we have weighed the truck ready to tow. Actual pin weight is 3,000 lbs give or take a few lbs so we are within limits on pin weight and that is the major difference between a 3/4 and one ton dually.
Now the Montana GVW is 15,805lbs and my truck GCVW is 23,500lbs.To determine my actual GCVW I must subtract the known truck weight from the RV sticker weight of 15,805 and we come up with 14,400lbs NOT 15,805lbs. IF the Montana were fully loaded to its GVW we would be OVERWEIGHT. We are not loaded to capacity and we are under the 14,400lbs. You can only do the calculations if you know the actual weights. Not easy to understand but understand you must.
There are also things like Tire load capacity stated on the Rv and truck tires.
That it will "pull it fine" means nothing and can hurt you.
