I have an '07 Quad dually work/personal truck with 65,000 miles on it with a hole worn in the passenger seat. I am a welder and carry a helper on 95% of the assignments I'm on. He's only about 25 lbs heavier than me, so I don't think that would count. You can definitely see some metal thru the hole, so the padding is not in place to prevent something like this. I bought an extended warranty when I bought the truck. Would the extra warranty cover something like this? I had a '99 that had 160,000 on it when I traded, and it didn't have any holes in it. Just sagging on the drivers side.
