Engine Brake usage

As I become more comfortable with the new truck I'm developing the habit of running the E/B in the Tow/Haul mode. I understand that the E/B is part of the turbo. Is the afore mentioned practice going to lead to premature turbo failure or damage the trans?
I'm wishing I had installed one on the Dually.

I have noticed, as many others have, that running the EB while in TH makes for some harsh downshifts while coming to a stop. I haven't tried it with the trailer hooked up yet though...

It is awsome with my 10K trailer!! Keeps the rpm up so the speed comes down. Yeah, it is harsh but I would rather have harsh than slushy!!

Yeah Its awesome when pullin some weight. Its not as bad when pullin but it still has the jerk of downshifting and engaging the EB. I haven't heard anything about turbo failure due to EB. I hope thats not the case

Bob, from what little I have read on the subject, I get the impression that not using the exhaust brake enough will can cause damage and turbo failure, but not the other way around. One of the parts guys at the dealer cautioned me to use the EB periodically. I have never heard anyhting negative about using the EB too much (if there is such a thing).

There are dealers that will tell you to use your EB 70% of the time, towing or empty... use it....

Just for clarification its an exhaust brake, not an engine brake.

and, if you don't like the way it downshifts in tow/haul with the EB turned on, use the + and - button to control the down shifts manually, that will smooth it out a bit too

I'm not worried about the turbo during the harsh downshifting. It's the trans I worry about....

Turn the exhaust brake on and leave it on. It will prevent the slide from sooting up and sticking. Mine has been on since it was new and with over 124,000 miles on it now, I don't believe you need to worry about premature turbo or transmission failure.

If these are so sensative and prone to trouble if you don't use them, it would have been nice to give us the option of programming the EB to be ON when the engine started.

On the cab and chassis once you turn it on, it is on until you turn it off. Doesn't matter how many times you start or stop the engine. Guess this is one of the many differences between the pickup model and the cab and chassis.

Well, after a couple of weeks of having to think about turning it on, I have reached the point where I just automatically do it when I start the truck. It's not that difficult...

Well, it looks like I got my answer. I'll just incorporate it into my start up ritual. It's only two extra switches to activate. It's not like doing a pre-flight on an F-18 .
My only gripe is the placement of the E/B switch. I might have to move it to the shifter stalk.
Thanks for all the input guys. I'm sure I'll have more questions as this truck is quite different than my 5.9 .
