OK, I have one. Where is best place to point it?

Wow, pulling almost 2x the trailer weight up the same guantlet. Same oil T as me (275), but much better coolant (221 vs 250), and 60mph vs 55'ish. But, outside air is only ~57 (vs. ~84), so I presume they didn't have AC on. My truck goes in for service Weds. What can be wrong with a brand...

RPM seemed to adjust into max torque range. It was not pulling uphill in overdrive. I did use tow/haul mode on some ascents, made no difference.

Yes, I am documenting everything, and counting the incidents and service calls, just in case it's a lemon. I don't think putting in full synthetic 5-20 would void warranty?

I was running 91 (can't get routinely 89 in colorado).

Interesting thought, but I can't imagine that's much of a load at 50mph in thin air at 10,000 feet. The frontal area is about 49 sq-ft, and the front is quite curved which must give some sort of streamlining.

Sure, no need for cash. I ordered RL 5-20 and will put it in before my next mountain pass run (aug 12). I video the guages the whole way up with a gopro, so plenty of data ;-).

Thanks for the clarification. 4'th it is. I looked inside and there appears to be two fans after the engine radiator. The upstream fan looks to be electric and the downstream fan (closest to the engine) appears mechanical. Next time it gets hot, I'll stop and look to be sure both are going (...

The truck is a 2021 Ram 1500 classic Warlock. 5th gen, yes? Would not the Oil Temperature Warning light come on if close to burning oil up? Anyone know at what temp the Oil Temperature Warning comes on at? And tranny temp warning? Thanks.

Thanks for the responses. I'll definitely do 5-20 full synthetic before my next trip over the divide (Aug 12). It goes into service next week. I checked fluid levels and they are fine. Haven't checked to see if both fans are turning (but last time dealer said fans were working). No leaks...

Max tow over 10K pounds, but only in ideal conditions, I understand that (crap advertising). But 3700 lbs? Doesn't come close to doubling the weight of the whole rig. To think I traded in my 20 year old Tundra 4.7. OK, it could only pull our trailer at 33mph (and getting 6.5mpg), floored in...

I recently bought a RAM1500 Hemi 5.7 3.92 4x4 to tow our travel trailer from Denver to west slope and Utah. We hoped to make ~6 round trips per year (24 ascents over Vail Pass + Ike Tunnel). Made 2 runs so far and it's a FAIL. Truck now has 1300 miles on it and I got the Engine Temperature...
