With exhaust gas temps in the 1400* range I donít think there is enough cool air in the stale area between truck and front of 5th wheel to cool it.
I havenít experienced any melting issues YET, but I have only been on 1 trip that I know my truck went into regen on (just purchased truck this year). This is something that I am concerned about myself, guess time will tell.
I apologize, I was referring top an active regen, which as Mad5581 points out, displays on the three DIC. Passive regens which you are referring happen several times for me as I drive mine daily about 30 miles to work. These do not generate ad much heat add an active one.
The exhaust on a stock truck does not get to 1400 degrees, not even Banks is trying to say that BS. With the exhaust tip below the truck, there's is always ample amount of air to mix with the exhaust stream.
