It's been pretty stable temp wise.
The peak temps I saw on our recent trip to Fraser island, fully loaded with two Expedition 134 boxes on the roof rack, were 95° and EGTs at 525°. Backing off/changing gear saw these drop pretty quickly.
This was with the Billy Goat guard installed. I'm not sure if it has much effect, but I wanted to reinstate aftermarket pieces that aid cooling the same as factory items to avoid the potential of creating an engine that has overheating problems.
I made this other guard to channel air flow through the radiator and prevent sticks going up through that gap.
