When you put your engine under stress Ie towing a caravan the exhaust gas will be hotter therefore worse for your engine it's just another way to maintain a healthier engine, you change your oil regularly so why not check that your temperatures are as they should be
I understand what you're saying but what can you do to reduce the heat if it's increased whilst towing, for example. If I had a gauge telling me temp had increased, I'd freak out first off all and then be waiting for something to happen. Might still have 300 miles to go
