Well, we're comparing two different things, so I guess I should have qualified that statement a little. My fault. They're going to introduce a light duty truck with a light duty diesel - or so the rumor goes. So I was comparing my light duty truck to the current crop of available diesels - all heavy duty with large diesel engines. So, let me (maybe more clearly) state that a big diesel doesn't make economic sense compared to a light duty gas truck in light duty use. Compared to another heavy duty truck with a V10 gas engine, you're right; I agree with you. I only do a little bit of towing, probably less than 1,500 miles a year, and less than 5,000#. But I drive 15,000 miles a year. For me to step up to a diesel would cost me about $10K in initial purchase cost, based on KBB prices. I can buy a lot of gasoline for $10K. I'm afraid to even calculate the cost of a brand new truck. YEs, a well cared for diesel should easily last 200K miles. But what about the rest of the truck? I'm not that confident.
