Well first off welcome...
Many will tell you here it is safe to all the way up to 5000 lbs, just make sure that that is including gear, clothing, fluids, in/on the trailer.
I tow a boat, with boat and trailer it is about 4400lbs with fluids and gear. Probably more like 4500 to 4600lbs I'm sure with all the extras in it like, vests, safety equipment, tube, and anchor. It will pull fine!!
ONE THING YOU SHOULD REALLY BANK ON IS 4WD!!! One of our other members only has front wheel drive and had some minor traction issues trying to pull a boat out of the water, but you'll be hauling a trailer and I would apply the same situation to you when going up hill or for emergency. When you get the 4WD system you are allotted a weight increase to a total of 10125lbs of GCVW... Vehicle, Payload, and Trailer= 10125lbs.
If you have any other questions let me know. Make sure you get a Weight Distrubtion kit and ensure you order the factory Tow pacakage!! You'll get all the benefits and a nicely intergrated factory installed OEM parts. Follow the manual for towing purposes, also make sure you put atleast on 1k miles on break in before pulling any trailer.
Happy Towing!!
