My wife and I have been camping for years with a couple of camping trailers we have enjoyed very much. We last spring purchased a class B motor home new and enjoy it very much but have had trouble pulling a 2008 Chev Malibu. It seems the car wants to do the driving and not the motor home. I am looking for help as I have almost exhausted my dealer and interrnet help as well as my pockel book for "extras".
