Question Heating problem

Hey guys
got another one for ya
when pulling a trailer (5x8 utility), even an empty one, my heater guage slowly starts to climb. when I'm doing 130 kmh in OD it will climb to about the 7/8 mark on the guage. same thing will happen if i'm not in OD but doing around 120KMh.
The only speed where my guage was untouched when pulling a full trailer was no OD and no more than 110KMH, it has also happened to me once when driving home on a very hot day last summer, I was doing 130km without a trailer in OD and the guage climbs to about 3/4-7/8 positionon the guage, almost to the full mark.
I've changed the T stat and nothing, not sure if I should go with an engine flush, change the rad or the pump.
any ideas
