Known overheat issues 4.7 RAM V8? EDIT FIXED

My 2010 Ram 2500 will heat up on the highway with the plow on.
Keep it at 45MPH max as the plow instructions state and all is good.
The plow will find the weak links on a truck.
Dodge 8 speed auto transmission are garbage for commercial plowing, they to like to overheat.
My next plow truck will be a GMC. LOL
