A quick search would indicate that the 3,000 lbs. you quote is empty. GVWR for the trailer is 5,835. Use 10% of the GVWR of the trailer to estimate tongue weight and add 75 - 100 lbs. for a good WD hitch. Now... what does the payload sticker on your truck say? Remember that gas, occupants and "stuff" all count against the truck's payload. The EcoBoost is a good motor. With 1/2-ton trucks it's all about payload.
