I have a 2003 Silverado 2500HD 6.0 with 10,000 lb. towing capacity per manufacturer. I would like to tow a 15,000 lb. GVW 5th wheel camping trailer. Can I make my truck capable of towing this much without spending too much?

 

I wouldn't recommend it. I have an 01 2500HD with the 6.0L and have pulled around 12,000 lbs with it but it's all the truck wanted to pull. You really need a 1 ton truck.
