I've owned an 08 duramax and now an 18. The 08 was a really good truck. My neighbor has 2010 ram and not very impressive. My 08 duramax did everything better has down. Cummins made there name with the 5.9 not the 6.7. It's not very impressive at all and is just riding on it's name from the 5.9 not what the 6.7 has done. My 18 is such an awesome truck not even going to compare to these older models not even close.
