Looking for advice, I have a 2006 Ford f-350 6.0 power stroke diesel. I bought the truck new almost 5 years ago. I had a few problems with the engine when it was new, never had the head gasket problem though. My warranty is running out and i can buy an extended 5 years and 60,000 miles warranty for $4600.00 from ford. I have 58,000 miles on the truck now and she runs great. I have to keep the truck for atleast 3 more years. Is it worth buying the warranty. I do tow a 40 foot 5th wheel toy hauler from time to time, it weighs about 16,000 pounds.Thank you for your advice
