That is 7640lbs total which leaves me 2260lbs for payload. but according to the scale slip I still have 3830lbs available on my rear axle...
Just stay under your trucks certified 6830 RAWR which includes tires/wheels and rear spring pack and/or if your state has a weighted registration. In my state we have no weight to register our private use trucks at so we simply carry weight determined by the RAWR in the case of a truck pulling a trailer.
If your going to carry more weight on the rear axle then you will have to up grade to higher rated tires/wheels and the rear spring pack or some type of aftermarket suspension help.
