Exhaust Brake

We had a great summer of travels in 2017, spending 42 days in our new 5th wheel. We purchased a 2015 Cedar Creek 38FB2 5th wheel....its 42 ft long.
We are pulling with a 2015 Chevy Silverado 3500 Dully Duramax Diesel with Allision and exhaust brake.

We had no trouble stopping.

Curious how you set your exhaust brake ???? 1..2..3..4..5..6..7 How do you know when it is set properly?? and pulling its weight stopping.
We have had no close calls stopping..but who knows.

Thanks

    Going about 20 mph, apply the brakes with the switch on your unit but not putting your foot on the truck brakes , does the trailer come to a smooth stop without skidding the tires in about 20 yds. If yes, then job done. If trailer brakes lock up and skid before you stop, lessen the setting 5.0 to 4.0 etc. If your trailer doesen't feel like it is stopping with the 20 yards the up the setting to 5.5 etc. Just takes a little trial and error.


    I used this procedure 3 years ago when we got our rig. Could never get the tires to skid even when set at 10 so I left it set to 10. Seems to stop OK, but would have been more confident that it was set correctly if I could have achieved a skid then backed it down. Anyone else experience this?

    I've got a 2016 Duramax. I think you are confusing the exhaust brake with the intregated trailer brake system. Exhuast brakes are either on or off. The trailer brake to your left can be adjusted by numbers. I would suggest putting it at about 4.5 and see if the RV brakes even with the truck then adjust from there.

    You lose me. There is no setting for the Exhaust Brake on my previous 2011 or current 2018 Duramax, Exhaust Brake is either On or Off.
    Are you talking about the setting for the integrated Brake Controller, as that does go from zero to ten??

    I have the same truck but it's a 2013. The exhaust brake is either off or on. I turn mine on.
