I have an 30 f350 drw and i pull a 40ft gooseneck all day long.I have installed a water temp. gauge and i get up to 200 while im on the hwy and up to 210 on stop and go trffic.
I was pulling race car on trailer about 4000lbs. 95 degrees outside running 75-80 mph and water temp was staying around 215 to 225. I put the sct tow program in before this trip for first time and did not know if it should be running that high.
