I tow a 3023 with a 1500 Dodge Quad cab 4.7 V8 eng. and it has the tow package. Does great on flat land , You have to keep checking to see if the trailer is there!! Went to Myrtle Beach SC. last spring and when I hit the mountains with 7% grade I could then tell that I was pulling a trailer !!!!!! and this truck is rated for 7000 lb towing cap. I would say that you are pushing it to the max with yours.The Rip
