B+ motorhomes

Just a quick update. I have been out of touch for the past couple of months. I now have 87K miles on the rig. I got stranded for the first time EVER, when the 8.1 "reduced power" light came on and would not go out - the vehicle came to a gradual complete halt as I was transporting three pets home from their annual Vet visit. Had to get a taxi to take them and my wife home. My USAA towing service towed the vehicle 50 miles to a Chevy dealer in New Braunfels Tx, where I knew it would fit and they would work on it right away. The culprit was the "throttle position sensor". The computer didn't know how much throttle I was applying, so it decided to shut it down to idle - I am told. Works fine now - added some preventive maintenance. Good for another 50K miles? Has anyone out there had carpet replaced? It is about time for that and reupholstery. I have never put so many miles on any vehicle I owned and intend to wring out every mile it is capable of!
