Elevated Oil Temps when towing - potential solutions

Hey all:

I live in the middle of a mountainous terrain of Western Canada, so we pretty much always deal with climbing steep terrain and mountain passes when camping with our travel trailer. I’ve been searching through the forums and getting lots of great info to help manage elevated oil temps when towing.

My current set-up:
Truck:

2016 Ram 1500 Crew Cab SLT, GDE Engine & Transmission Tune, 3.55 gears, Timbergrove ASAM, upgraded 275/65/20 rims/tires (17” original factory stock – I know the larger rims/tires are detrimental for towing, but appearance matters too…)

Travel Trailer:

2020 Springdale 220BHWE; 4,900 lb dry, ~6,600 lb loaded

I have snipped the stats on one of the larger mountain passes we travel below—I will hit the derate message for oil temps (130 C) during the ascent, and I currently follow @VernDiesel advice of keeping <3,000 RPMs and the speed ends up in the 60-70 kmh range.

Looking for some additional input/feedback on potential improvements with helping keep the oil temperatures down. Here is what I am thinking and have gleaned from other forum members (@Bounty Hunter, @Brokedownbutgood - always appreciate your contributions to the forum)

Any additional thoughts, feedback, and suggestions would be appreciated.

Also from the west, we have camped along Hwy3 in the past. Been there with my 2016ed 3.92 axle and 30feet travel trailer that we frequently use. Scales at 7000 lbs loaded. The truck is gde hot tuned and with the longhorn honeycomb grill and keeping the sustained rpms under 3000 never ran into derate situation. With 3.55 gears you might want to try a shorter tire. 3.55vs3.92 might be the difference between a derate or edging past a derate by a small margin.

This is the type of grill I am happy with, both looks and performs flawlessly towing my TT.

Talking about Intercooler relocation, has anyone tried this endeavor yet?

Hi: SlowRoller... Is there an app to use to profile the "Hot under the collar" feeling I get when towing. I know it's caused by the other "Id. jets" on the road. They'll do anything to get by us...ANYTHING!!!

She's the real longhorn, we people with a longhorn grill can only pretend to be a longhorn,, my next truck will be a pearl white longhorn if they keep making em with chrome bumpers.
