That site is not to be trusted. It doesn't take into account your options. The sticker on your door jamb is what you need to use. The GVWR is weight the total weight you can put on your axles, not what you're capable of towing. The main thing you're looking for is your payload capacity - it's the sticker that says: "The combined weight of occupants and cargo should never exceed" and then it will list the payload in KG and LB's. Let's use my truck as an example. My sticker says "596 KG or 1316 LB" - so my payload capacity is 1316 lbs. Now, that trailer you're looking at says the "hitch weight" is 806 lbs, so I must subtract that from 1316 because that's the amount of additional weight it will put on my axles (aka cargo). That leaves me with only 510 lbs of additional weight in my truck before I max out its payload. Our trucks can PULL much more than they can handle on the axles. All of the options the Limited has actually reduces its payload - dual pano sunroof, heavier 22" wheels, larger front spindles, auto side steps, etc. Yes, you can pull a 6300 lb trailer easily, just keep your payload in mind. ALSO, when you load up that trailer for the trip, you're adding weight to it as well, so add 15% of additional weight in the trailer to the hitch weight (thus taking up more payload). But it's still way more efficient to put as much as possible in the trailer than to load it into the truck because it's not a 15% deficit, it's 100% loss. Meaning, if you put a 100 lb generator in the truck, it's 100 lbs lost to your payload. But if you put in the trailer, it's only 15 lbs lost to the payload.
