Let's go through this. Your Dodge has a lockup converter. My bus does not. Your old cars weigh 3-4000 pounds. My Excursion weighs at least 9000 without all the extra crap I took and my trailer weighs at least 2500 pounds. The GVW of the bus is 23,000 and weighs 16,100 pounds. So I am weighing in at over 27,000 pounds with the Ex on the trailer behind the bus. I could have just pressed on and ignored the temp gauge and dealt with whatever happened in the middle of nowhere. I cross over 7,000 feet at least twice on the way home. My decision was based on caution and nothing else. My bus probably never had more than a couple thousand pounds of students in it. It is in excellent condition, so why ruin it. Every time I hit a small hill, the temp would climb from 180* to over 210*, then the fan clutch would kick on and the temp went down. All this while on the flats of Texas.
I don't know if you are aware of the wonderful split radiator that International uses but I feel it is inadequate for heavy duty use. When I change the trans and radiator to a larger one, I should be able to tow a house without problems.
