BradSD, some good info from the previous posters. Let me add some of my Ram 2500 towing pearls to your information.
1. Please be careful towing with your rig, because even though "1500" trucks and crossover vehicles are touting high tow rates, and
RV dealers will let you leave with anything which will move the trailer, you can find yourself in a bad situation real fast towing with a smaller vehicle. I'm not
doubting your towing ability, nor driving/towing skills. I'm only saying what I've seen happen in real life while towing on the road. IN the blink of an eye, you can find the the "tail wagging the dog", from say, a crosswind, or an aggressive driver causing you troubles.
2. With regards to engine temps, and such....When approaching a grade, I would select the lowest gear which doesn't approach the redline, as this will allow the whole machine to operate in less of a "%load", or what amounts to lugging the engine. You'd think the engine tranny would automatically take care of this, however, remember CAFE and you'll understand. I've watched my EGTs (exhaust gas temps) climb on my Ram towing our 5er, and just gearing down 1 or 2 gears allows me to maintain speed while maintaining much lower EGTs. You'll quickly get used to how your GC feels when it's starting to lug. Just read the terrain ahead, and even on a mild grade just downshift 1 or 2 gears and let everything "relax a bit". Then, if you are still feeling increasing throttle input, maybe gear down one more. The GC shouldn't let you downshift into an over-revving situation.
I do not know this to be a fact with our CRDs, but I would bet the engine would "defuel" before you will melt anything EGT related. Said another way, I don't think the 3.0 is gonna grenade, as I think it has safety factors and protective logic built into the tune.
3. Also, selecting a lower gear on grades helps protect the transmission, again by giving the transmission some mechanical advantage.
IF you are moving slowly at a campsite, or having to slowly climb a moderate to severe grade, select low range, if you have that option. That will really alleviate heat build up from a slipping torque converter. (Many a 2500 has boiled it's tranny fluid pulling up some tall grades, in high range, leading to parking areas at our motorcycle races.)
4. As fun2drive suggested, check into the Amsoil engine oil offering. If you pay a small yearly fee, you can get the oil for 8.50 a qt.
5. The oil life monitor will take into account your driving habits and you can expect a shorter oil duty cycle if you tow much. If you prefer to stick to your own oil change schedule, that's ok by me as well.
Just wanted to throw in a tow pic of picking up our 5er a few months ago.!
