On the last day of February, my wife and I were traveling across Oklahoma on highway 412, or the Cherokee Turnpike. As we entered into Arkansas I flipped my exhaust brake on. At the bottom of the hill I could only run in 1st gear. I have a Cummins/Allison power train. I got it off the road and got my book out. I reprogramed the transmission and everything worked. We proceeded East on 412 to about 10 miles West of Alpena, Arkansas. As we went down a three legged hill I flipped the exhaust brake on again. At the bottom of the hill I could only run in 1st gear. I got off the road and fooled with it, finally giving up. I called Good Sam, they sent a wrecker which pulled the motor home back to Springdale, Arkansas. The Freightliner place found that the switch that controls the exhaust brake was defective, which they replaced. The wrecker bill was $700, which Good Sam paid and the repair bill was 265, which I paid. My point is this - the money I paid Good Sam for breakdown protection ($95) saved me a lot of money. I am thankful for the quickness that Good Sam gave to my need. Jack092
