Thank you everyone for the compliments and suggestions. I am pretty much leaving it stock as-is.
Over the weekend just doing routine maintenance, oil change etc.. I discovered they did buy a K&N air filter for it so I cleaned and recharged it. However, it didn't fit right in the airbox preventing it from sealing properly. I found that the filter had an extra tapered 1/2 inch projection of molded rubber on the top hat. So I carefully trimmed that portion off and it sealed like it should. It is the correct filter but it that projection probably was intended for a different application I guess.
I also ended up ordering a set of black/red Cal Trend seat covers and a black powder coated bull bar for it that I will install later this Spring, Spring or an extended break in the weather is when I really want to flush that Dexcool out. That stuff wreaked havoc on my old Jimmy. The intake gaskets when I replaced them were so deteriorated from that stuff. Hard to tell where I am with this truck since I see no evidence of seepage around the intake. They may have been already replaced.
