[Ivan Augustine] I recently purchased 2001 3/4 chev 4x4 with a heavy duty trailoring package to pull a 31 ft. Jayco Travel Tr. I just had it out last weekend. I noticed a knock/bang when I was slowing down at stop signs before I came to dead stop. I pull on drive with the tow/haul mode engaged. It does not make the knock when I am not pulling the trailor. I talked to the truck dealer and they said it couldn&#039t be the truck. I am wondering if anyone has had a similiar experience? The thing I am thinking about now is the electronic brake, could this cause the knock/thump? I use a vouageur brake.
