I didn't notice a change in temps going up mountains at all. Did you get the max tow package? bigger rad/trans coolers.
When I bought my Ram Ecodiesel, they were hard to find. Dealer only had 2 on the lot, neither had the tow package. Still it tows great, plenty of power and torque, might install a brake controller, maybe switch out the restrictive "Bighorn" grille for the" Laramie Longhorn" grille. Towed a 10,000 lb boat the other day, oil temps rose a bit on long hills, but economy was outstanding= a hair under 17 mpg. My hemi would have done it fine, but have been revving at 4,000-4,500 rpms on the hills, gotten 10 mpg if lucky. BTW, the boat owner rode with me, he has a 2500 Silverado with gas V8 and he was quite impressed how easily the little 3L towed his boat.
