JSkid,
You might be right. I wouldn't know, as I haven't worn one out completely yet. My 2007 Dodge Ram has 100,000 miles on it right now, and it's still running strong. Hoping that it will last for quite a while longer, as I can't afford a new one right now.
But while we are on the subject of "will do that", please think about how often you see Nissan's and Toyota's with a work bed / welders bed in back? How often do you see a Nissan or Toyota pulling a fifth wheel camper? Tundra's and Titan's are still 1/2 ton trucks with no diesel offerings, and until they enter the big boy market, the big three will still have a ton of market share in that arena.
All the best,
Glenn
