The good news is that you have the six speed transmission that will give you a towing gear, either 3rd, 4th, maybe 5th, that will put your engine in a good rpm range for towing your trailer regardless of the rear axle ratio. The diesel guys will now tell you how they tow in 6th. We, who have gasoline powered tow vehicles, generally don't.
