Oil analysis from Valv Extended Protection 5w30 with 2000k mile heavy trailering through the south in June vs Mobil 1 5w30 with no trailer towing. That Extended Protection is good stuff. This is with 4.8 V8.

If you think of it, post this in the UOA forum too. When people post UOAs or VOAs in this forum, it's harder to come across them in searches.

About how heavy was the trailer?
Well, gross combined was 11,900 lbs. I can’t know for sure how heavy the trailer was (tongue weight vs trailer wheel weigh) however, empty weight of the truck is like 5700 or so (If I recall). GCWR of that truck with 4.10 gears (I have 4.11) is 13,000, so its having to earn it’s money. Went about 2200 miles with it.
