2011 Ram 3500 CTD

Thanks for the info folks and I have one more question relating to 5th wheel and goose neck hitches; the truck came with what appears to be a goosneck hitch in the bed which is common in this area for horse trailers, etc.

They will be installing a slider hitch for a 5th wheel so I assume the gooseneck hitch must be removed, correct?

Tell them to drive it like they stole it. Those vintage 6.7s need to be worked hard most of the time. Chris

Overall great trucks. Make sure all applicable recalls have been addressed: https://www.mopar.com/en-us/my-vehicle/recalls.html

Some common problems: O2 sensors throwing CEL, seat heaters malfunctioning, intermittent radio shutdowns, steering column/linkage play...

Birds climbing into the front wheel wells and building nests...I guess this is unique to me, but still a big PITA!

No def but EGR cooler cleaning, crankcase vent filter replacement at 67,500 miles. pay attention to coolant requirements, different years different coolants as listed in the diesel supplement.

Got it, thanks.

No DEF came in 13 year models
