So picked up a truck today. Just a 3/4 ton gasser, had a plow on it. So I knew I didn't have room for truck with the plow on the trailer, so I threw the plow on the truck, and the gasser on the trailer. All was fine for 40 miles of the trip. I stopped at a store where the truck idled for probably 20 mins, got back going and less than 2 miles down the road it spiked the temp gauge to like 230. Pulled over idled the temp down to like 180 and hit the road again. 5 miles later same thing it was like 40 degrees out wouldn't think that would be hot enough to over heat??? Trucks a 08 6.7, trailer was probably only 7500lbs
