I love my new truck, but... never owning a diesel before I'm wondering if I did the right thing. Now I have to worry about fuel gelling, whether or not I can use biodiesel, plugging it in during the winter and, if the fifth wheel that weighs 11,900 dry is too big for the truck! The RV was listed as 3/4 ton pull ready. I guess I should have done the 3500 duelly but the 2500 is nicer to drive around town. I only pull MAYBE three times a year and not usually far. Was I crazy to do this? Will I look back and think I was foolish or think that I did the right thing and love the truck more? Is this just a first time diesel owner doubting his decesion?
