Heck, I'll throw my $.02 in... First, it's nice to see, that after all of the flaming brand wars I've seen on TBN in the past, cooler heads are prevailing. Kudos to everyone for keeping it civil, I mean that. Now, as far as dually vs. SRW, great question. I've always owned SRW, because my truck spends as much time off road as on. I have owned a sampling of all of the big three diesels, in about every flavor offered. Each one had its good and bad points. Ford experience: 7.3 Powerstroke, multiple oil pans, HPOP issues. 6.0 Powerstroke, EGR and oil cooler, head studs. 6.4 Powerstroke, EGR cooler, $hitty fuel economy. 6.7 Powerstroke (2011), whacko tranny, engine ran like a bull. Chevy experience: 6.6 D-Max(2007) Fast! But, tranny cooler lines, IFS = Suck! Did drive very well empty! Dodge experience: 5.9 12v, killer dowel pin. 5.9 24v, lift pump failure(had 5 sp manual behind it, so rest was bullet proof). 6.7 common rail, pre-DEF, $hitty fuel economy. 2013 6.7, DEF, good fuel economy, AISIN tranny rocks, new front end tight. Will report back as I add miles. I do think, for your needs, you might want to go dually... Pic of my latest rig ;-)
