I have installed some winter front I bought from Eric Buckle on TDR. These work pretty well so far but during colder snaps, the engine temp does tend to drift down from normal operating temp. if a load is not kept on the engine. A few of you I think AV8R and Dargo have Cummins trucks and anyone else as well; just curious as to what you use for winter operation to aid keeping the engine operating temps. in the sweet spot? I tried a winter front that Cabela's had but it did not fit very well esecially with my wind/bug deflector.
