Coolant level is fine and there appears to be no lasting effects. Dealer said this was "normal" and that engine temps are meant to run high (30mins @ 150C is apparently ok!)
Having towed with this rig in full camping weight in warm to hot temps before (in low range and deep sand for 3-4hrs at a time with no issues) I was very surprised that this overheating would happen.
Help please - is this a 1 off due to conditions or have others had similar issues?
When you first got the warning, or noticed the temperature was going up, did you immediately slow down and drop to a lower gear, turn off any AC, or other head loads?
Continuing to run until it went to limp mode seems like a strange way to continue unless you were within walking distance of shelter, cooling, etc.
