At the moment, it's my daily driver, though it occasionally hauls Boy Scouts and their gear on outings and moves my college-age son from apartment to apartment. I may do some towing, but none so far.

While I understand that diesels are very heavy-duty engines with a lot of torque, I am also under the impression that proper cooling of the engine oil, etc. are critical - more so when really working (towing).

I could use an education on the design and test considerations for things like grille blocks, of which I have seen several examples on the site. Any suggestions welcome.
