Ram exhaust brake at slow speeds.
This issue was brought up in another tread and I didn't want to hijack it so.. On our first trip out with the new TV we went to the NC mountains...of course :B. Going up the 6-7 % grade was awesome...

The one guy had the right idea, get er in 4 low if you have to then you can work the upper gears at higher rpms. BUT if you're on twisty pavement that requires going that slow then you're making prety sharp turns. Get ready for the front axle to buck in 4wd.
That's the beauty of having locking hubs which no one offers anymore (no, Fords don't disconnect either. Basically the hub locks are a sales gimmick). You get 2wd low range.
For those that still don't understand why the factory turbo brakes don't engage in 1st gear, is the trans always slips in first gear, doesn't lock up the TC. That's where the last of the hand shakers shines because you can use a retarder in first gear.
I've never felt the need to put my truck in 4 wheel high, much less,4 wheel low when towing on type terrain we've been dicussing here.:h
My tranny is still slowing truck when it downshifts to 1st gear,and will continue to slow it.
Me either, on dry pavement, but the op apparently couldn't hold his load LOL, with the jake brake and service brakes at his speed and gear, so..........
Btw, you won't hurt a thing running in 4 wd on dry pavement.
I've driven and towed many thousands of miles in 4wd. Granted most was snow but dry stretches didn't blow up the truck.
Personally I would just not point my big 5ver down a twisty grade like that if the truck struggled to hold back the load.
I have used 4 wheel high and I know that I could run around on dry road in 4 hi, and truck would be fine..I'd use it if road conditions merited it..but again, have never needed it to help slow load down when towing.
Totally man. Me either, but OP sounded like he made it halfway down into Gila and was having issues. At that point, drop er in 4 low if you have to and creep down.
Not a very good idea if you are locked in 4 low on dry pavement , if having to do any turning. Those front tires grab pretty hard. A straight shot would be okay.
I converted my previous truck from auto hubs to manual locking hubs. Just like the old days being able to have 4 low without 4 wheel drive.
