6.0L towing 5K question

Hello, I just bought an enclosed 28x8 car hauler that my dad an I plan to use for are ATV trips or during moose hunting season. My total trailer isn't extremely heavy at 4995lbs loaded. I had wanted to ask should I be towing in tow/haul mode all the time? My concern is that in overdrive my crusing EGT is 900-1000F in od. I would suspect this to be because of the 35" high tires and the rear axle gear ratio of 3:73:1. So my question is, is it safe to run in tow haul mode until I reach highway speeds then I engage overdrive. Any hill I come across I always disengage overdrive to build boosts to keep the EGTs in check. I'm just concerned whether it would be hard on the trans. I have towed with my SD before but never any kind of weight that you'd actually feel behind you. I should also note that my truck has a powermax turbo, and a tow tune from gear head preformance.

Any input or insight would be greatly appreciated. Thank you in advance

I have a 7.3, so no tow haul on mine.... but with my work truck, i only use tow haul around town or if going down a pass and want to use it for braking. 900-1000 degrees is just fine, you can run 1250 all day long so long as you dont go above it for a long period of time.

You really wont even notice 5k behind you. Watch egt's and your tranny temp and you should be fine. So long as im on flat terrain i haul my fifth wheel in overdrive with no problem

I run in tow/haul mode anytime I am towing. Tow/haul mode does not keep tranny out of O/D. Tow/haul just changes how the tranny shifts

Like stated above. T/H Will still shift into OD it just needs to be using less engine power before it will shift in and lock up the torque converter. It's quicker to downshift to keep from driving "under the turbo"

I wouldn't use it. Waste of fuel in my opinion. No need to shift at 2500 RPM towing 5k

I have Amsterdam to Malaga(spain) comming up next week.
same weight as the O.P Same tires and gear ratio.

to me it feels more natural to keep it in tow mode as the engine breathe more air and has better cooling.
But with our european diesel prices i do not wan,t to waste fuel so i wonder what would give a better Fuel mileage Tow mode or not, without frying the trans ofcourse.

I have the gearhead 8k tow tune i do not know if that helps or not.
speed limits 50 miles per hour,...that would not even kick it in OD in while tow mode.
When i push the Tow/haul button off it kicks in OD at 50/55 but at 1600 isch rpm,EGT Rise to 900 and it just doesn,t feel right.

Maybe 35 tires and a 3.73 ratio and a 4 inch lift is not an ideal set up for towing @ 50Mph

if you destroy any parts with 5k, you either need to slow down or you had issues before hand.

I dont use T/H unless I am doing a lot of braking.
