Mine ended up surviving two trips pulling a trailer loaded with furniture and appliances across 255mi and 2 mtn passes. But boy howdy with 35s does it ever feel tired. Kept an eye on coolant temps and fuel trims the whole time. It must be decently healthy because at all load ranges within the map it seems to be within 4% of 0 trim. It's just gutless, I let it eat on the passes watching to see what it would do. 206 to 210 degrees most of the time under heavy load and a brief moment of 217 but it never ran away. As soon as I go back to cruising on flat ground it settles right back at 195 and mostly just stays there. This is far from my first time towing with it and far from my first time pushing it hard, towed plenty at or above 6k lbs when I was in Arizona but my first time watching it do its thing with the TOYOBD scan tool.
