Throughout the 1970’s, sales gradually dwindled. In 1972, GM changed the model designations from PD 4108 and 4905 to P8M 4108A and 4905A, respectively – equivalent to its transit coach naming convention. Then finally in 1979, the 4905 was renamed H8H 649. An Allison automatic transmission was available on these last two years of production. The final Buffalo produced, No. 233 pictured above, was delivered to California-based Eastshore Lines in 1980.
Where is the bus located? Is it the one I saw recently at a shop in the Milwaukee area?
A few questions for you to consider - Why do you want a class A rv?Why a bus? Why do you want to convert your own? For me, A class A because I like having my fridge & bathroom inside what I'm driving. A bus because it is more robust than sticks & staples. Convert myself because I thought it would be cheaper. Turns out, my plan to convert was going to cost way, way more. I was able to get a very nice, well built & maintained RV for less than half what the conversion process was going to be -- AND, I was able to use it right away.Good luck with your quest
