You're right Vin, don't want to give him misleading information I agree with all of your points. I just wanted to state the simplest way to increase his towing capacity is gearing. A 1/2 ton truck will always be a 1/2 ton truck. If you put two side-by-side one with 3.42 and one with 4.10 given all the other parameters are the same the towing capacity is higher, and easy to figure by looking in the Owner's manual. He may be able to increase to 6500+ lbs capacity in gears alone. Of course some power upgrades, helper bags, trailer brake, etc..would also help. And a transmission cooler is a MUST for any towing.
