My heart was pretty set on a duramax as of about a week or two ago. Then after doing some more "digging" I found out how much the costs to repair a duramax are, and started rethinking it. My mechanics said that a 7.3 powerstroke is a good engine and much "cheaper" to repair than a duramax (thats all relative to diesels though). The fact that the repair costs are less than a duramax make me feel a little better about the engine too.
The one that that I really like on the duramax trucks is the allison tranny. I wish I could get an Allison on a ford. I hear of very little problems with Allisons and they have a very good reputation. But I don't hear that many tranny problems with fords either so, I have to consider that. And I won't really be putting much strain on a tranny either.
