Have you ever had an overheat alarm go off on your GMC??
No, but we just got the Mountaineer. In summer with the 28' Sportsman in East TX the fan would be so loud you couldn't carry on a conversation.(my gauge would never move,but IIRC the fan doesn't come in until around 217*, so I know the temperature was climbing) This would be on TX 43 between Henderson and Marshall, just small choppy hills. Some of the LLY engines seem to be worse than others. Guess I'll find out this summer about ours. We hope to hit the high country.
