The problem with the 8.1 engine in a motor home is the 25 foot fuel line running right above the exhaust on the left side. You have a sealed floor right above the frame rails. When driving slow or lots of stopping at lights the fuel will boil in the line causing loss of fuel pressure. It can get 180 degrees under where the fuel line is. Best fix is the Banks headers with single exhaust on the right side of the frame. That fixed all the problems on my 2006 Winnebago 38J Workhorse W24 8.1 and Allison 6 Speed transmission, 35,000 miles on coach.

Sorry to hear that you Winnebago has so many problems. We recently purchased a 2006 Winnebago Voyage 38J for $30,900. Had a new generator and transfer switch installed by the dealer for $6.400. The engine did not run good, A Chevy RV shop found the fuel filter was clogged as well as the fuel pump being clogged too. With those 2 items fixed, we now has a good as brand new coach that we are loving, now more problems have been found. We also had brand new tires installed as the one on the coach were 12 years old and cracking. Total investment is $51,000, and the coach is worth $70,000 now now. I believe we made a good investment. Our coach has always been in southern Florida it's entire life, and we are only staying in warm places year round.
