Exhaust gas temperature and towing
My 2004 Ram has 325 horse and 600 ft-lb of torque. I find myself bumping 1,300 degrees of EGT before I max my power capability. I like to keep it below 1,300 so I slow down as I have already geared ...

I have a 2012 Ram Laramie Longhorn short-bed crew cab w/6.7 turbo diesel HO (350HP/800lbs torque) towing a 29ft Montana and use an Edge Insight to monitor a whole range of temps and pressures. Turbo timer idles until PTEGE 350F. Never put in the pre-turbo sensor for fears of the pyro failing and losing a turbine because of it. It does in fact happen. Post turbine temps have never exceeded 950F and if I get at all concerned I downshift to keep the engine in it's optimum power range ~1,900 RPM. That simple downshift sees temps drop by 200-300 degrees. IMHO, if you're RVing you aren't in such a hurry to get anywhere that warrants risking an engine/turbine.
