Dropping my deposit today on a JLURD and started to wonder last night about it's cold weather performance. For those of you with the 3.0 in northern climates, do you notice any differences when the engine is cold? Did you opt for the engine block heater (I'm planning to)? At what temps do you normally plug in the heater? Aside from all the other hidden "fees" of owning the 3.0, (def fluid, price of oil, etc), what else should I know before I commit?
