Hi all. I'm towing a 25' travel trailer that weighs about 6500lbs loaded and ready to go . I live in Calgary and just took a trip out across the prairies and was surprised to find that on moderate climbs (shorter steep hills coming out of Drumheller) that the temp gauge spiked very quickly. It hit one mark back of the red zone on the temp gauge. I was watching the oil temp and watched it hit 118 C or 245 F. I am nervous as I will be going camping through the Rockies and know the passes will be far more demanding. Anyone have experiences like this? Will the temp hold on a long climb for 10-15 min?
