To me it simple subtraction Truck 6500 tow cap - Trailer 4300 lbs...no brainer. I guess thats not it works.
Unfortunately, that's not how it works.
The reality is that your truck does not have a 6500lb tow capacity, and the trailer does not weigh 4300lbs. This is because you put stuff in the truck which lowers its tow capacity, and you put stuff in the trailer which raises its weight.
Depending on the trailer manufacturer, that 4300lb weight may be with no options, no battery, no propane. Two tanks of propane and a battery will add about 100lbs. Air conditioner, another 100lbs. 30 gallons of water is about 250lbs. That's not counting your pots and pans, clothing, food, tchochkes etc..
The 6500lb tow rating on the truck makes the assumption that you are using 100% of the truck's payload capacity for trailer tongue weight. Meaning, the truck exactly as it rolled off the assembly line. No bed cap. No passengers. No firewood, bicycles, kayaks, tools, or toys in the bed.
