More info is needed, what truck do you have? Is it a DT or DS truck? Trim level, cab style, and rear end ration all factor in heavily. The sticker next to the one you took a picture of is your vehicle loading sticker, and will give you your trucks empty payload number.
Also, there are three trailers listed in the second chart. Which one are you looking at, the numbers for the pin weights vary by 600 lbs. That's not insignificant. And don't forget, you need to factor in the weight of the 5th wheel hitch as well in all this. And all of the trailers listed are well into the towing capacity of a 3.92 DT truck, so if you don't have the 3.92 gears, then it's a no-go already.
Bottom line is though, despite what trailer mfg's may say, most half ton trucks are not rated or designed to pull 5th wheel trailers. The only truck mfg to publish 5th wheel numbers is Ford, all the others specifically leave out 5th wheel towing ratings and instructions, some even specifying to not tow a 5th wheel at all.
