I've gone 45-50 down Highway 82 with CDL engaged in really crappy conditions. You're not turning tight enough at that speed to bind anything up, I didn't slip, but it's impossible to say if that was because of CDL. It just gave me piece of mind.

yeah I'm the same, I can't decide if the CDL is better on or off in these conditions. The worst conditions IMHO are pavement with patches of ice. I have to really hold on for this. Snow is fine.

Anyone else locking the CDL in snowy conditions on the road?

I personally do not lock anything on ice / snow.

From experience, I can tell you that a Discovery driving at highway speed (6 lane highway, probably 45 MPH) at dawn in light-snow-falling-and-melting condition hitting a icy (1/2" layer of ice) bridge can avoid a Renault Super 5 while that car was doing two 360 degree loops.
The Discovery did not have the CDL locked, my mom was driving it and I was driving the other car. I got surprised, _touched_ the brakes trying to slow down... too late.... big error! nobody got hurt, touched the side rail, needed fender job only, drove the remaining 100 miles; can't say the same about the totalled ford-taurus-equivalent car 200 yards away.....

(Renault Super 5 info: http://jpracing.racerplanet.com/modu...thumbs/184.gif or http://commons.wikimedia.org/wiki/Im...ult_Super5.jpg)

Here is my (unverified) theory:
- On ice and snow on regular paved roads, you want to avoid any tire slipping which a locker could induce. This is also why you typically will drive a 5-spd "one gear higher than normal" (not sure if automatic can do anything about it except keeping a very very light foot).

- On ice and snow on non-paved road or deep snow on paved roads, I'd lock the CDL because in this case, you are likely to need to go up/down irregular terrain and would loose traction quickly otherwise plus you are at much lower speed (max 25 mph?).

Now, I'm sure someone with more experience can give us the "official" word.

I ran almost a full 12 hours through blizzard coming up the East Coast a few years ago. I found it more helpful to keep the truck locked in high almost the entire time since the conditions were so bad and I dont recall us ever getting over 30mph..

What's the trick to changing from H to L (or vice versa) while still moving? The manual says it can be done but I haven't been able to put it in practice without making terrible noise. Is it also possible to engage/disengage diff lock while moving? I was up on the mountain today. Drove on ice packed roads with diff lock engaged. As soon as ice went away I attempted to disengage the diff lock while moving. Not a good call. It made a big bang noise and I thought for sure I broke the transmission. Does anyone have advice for how to do this without destroying your gearbox? It would be really nice if you didn't have to come to a full stop.

Just going from personal experience here, I wouldn't try going from H to L while moving. That's such a radical change in the ratios, that it's going to shock stress the driveline since there's no clutch in the system at all. The diff-lock can be done, but I only do it at slow speeds of 5mph or so, you get a lot of tension built up in there (as you noticed) and if I can I prefer to do the good old 5ft reverse first.
