I read this topic quite a bit here so here's PUT.com attempt to pencil whip the cost of ownership comparing some gas engine trucks to the new RAM Ecodiesel truck. Link Enjoy...
I love gas motors and I use to love diesels before....well, lets just say prior 2007.5. With that said I would bet any of these 1/2 ton diesels that are coming to light would make towing a more enjoyable experience than my 12' 5.3 or dare I say even my previous Ram's 2500 Hemi.
