New info: We are about 1000 miles into our summer trailer trip and the exhaust sensor failed. This was a couple days after getting a P0402 EGR code. And coincidentally a few days after seeing EGT of about 1200F for a short time climbing a minor hill in what appeared to be a reasonable gear. I backed off a little and got temperatures back down to around 1000. Otherwise, tow mode seems to select a reasonable gear and EGT stays below 1000.
Pray for us to get the backordered sensor in less than a month... I can get aftermarket right now, but I don't dare walk away from the warranty.
