Ok guys...I currently have a 2006 1500 Big Horn Edition w/ the 5.7L Hemi w/ 41K miles...in town a respectable used car dealership has a 2004 3500 w/ the 5.9L Cummins w/ 42K miles...(both automatics)they are offerinng to pay off my hemi and sell me the diesel for $22,900...my Hemi just is not have the power or hauling capacity I want...I drive only about 3 miles to work each day...should I go through with the deal? Will I have problems w/ the 3500? Will my low mile driving hurt the diesel? Thanks a million!
