I think your payload is what will get you (it usually does). Figure an average 22% pin weight. Also, the curb weight is usually never real world..I usually add another 100 lbs. right off, and it maybe more. Don't forget to add your hitch hardware and anything else you'll take with you.
Using the numbers you provided, 2118 - 100(just in case) - 75 (hitch) - 50 (groceries) - 300 (occupants) = 1593 available.
As a guess, I usually split the trailer dry and max numbers. So...about 8040 lbs wet and estimating a pin of about 1768 lbs.
Overloaded on the truck by around 200 lbs. Of course, that's all guesswork but the chances of overloading something are fairly high there. If it's just 200 lbs......well, your call. It's not GROSSLY exceeding the limits but (DISCLAIMER: you should never exceed the weight limits). What would discourage me here is your loaded weight is almost 90% of your max capacity and, in my experience, the closer you are to max, the less you'll like the performance.
