ANY SCORCHED RV TRAILERS?
I just bought a new truck, and then I began to consider the potential for heat damage to a fifth wheel travel trailer during an exhaust filter regeneration. The tip of the tailpipe on my new Duramax is only a short distance from the trailer.
I’ve searched the Internet and can’t find anyone reporting a problem like this. The GM literature says the exhaust tip was designed to “moderate” temperatures at the exhaust tip, but I do wonder whether driving for a few hours on the highway during the summer would cause any damage to my trailer.
I would like to know whether you have encountered any discussion about this. Kyle Werner Fargo, ND Actually, we have heard from Rvers who were initially concerned about the same thing as you, but after a season of towing they discovered that the possibility of trailer damage due to a hot exhaust was not a problem. Because of the higher average exhaust temperatures produced by the engine while towing, the regen system will likely never activate. Also, GM programmed the system to not begin a regen cycle if the vehicle is moving at a speed of below 30 mph. These combine to reduce the possibility of higher-than-normal exhaust temperatures at the exhaust tip. Be happy, no worries!
