My truck does well in the winter with what I have. Just get a winter front to close in the grill. I use the stainless steel grill inserts which look decent as well. I installed a manual push/pull throttle cable to bump the idle in the morning. When it gets cold I fire it up a little early, bump the idle and run the exhaust brake. When I get in 15-20 min later it's toasty warm and runs well.
