I have a 2010 1500 with 3.92 gears, i towed my 28' travel trailer and loaded it weighs about 7700 lbs, any time i hit the hills the engine temp would climb (250) along with the engine oil temp (250), the trans temp would be fine though. the ambient air temp was around 80, i checked the coolant level and all was good. I am just surprised at how easily the engine temp would climb as i had a 2006 ram that never even came close to heating up. i use the manual console shifter and kept the trans. in 4th gear has anyone else have something similar while towing?
