You need to look at the tire loading/payload sticker on your truck, rather than looking online. If yours shows 1800+ you may have enough payload. Only a scale will tell you actual weights. With a FW, your TV RAWR is most important.
Without knowing all the actual weights of loaded truck, and loaded FW, I won't say it will not work. Also, I do see many towing heavier FWs, with lesser trucks than yours. Yes, they are way over weight, and it is obvious. I think you need to gather all weight info, and decide yourself, if you are okay towing with what you have.
Hope it works for you,
