I changed out my tranny fluid and went back to 10w in the engine and it's been doing ok...
I don't know if I just bought time or if I had defective oils in there. I'm sure some damage was done but I towed the camper twice for 40 miles each trip and everything measured ok on the gauges.
My plan now is to wait till the 2020 leftovers are discounted for 2021's and look for a new last year truck. I missed my chance in Jan/Feb this year. I looked at a new leftover 2019 for $32k had everything I needed but was a GM and I didn't bite because I wasn't sure I wanted to buy another 6.0 GM.
