I had the 10th Winnebago Centauri made by Winnebago. It was not supercharged and that little 4 cylinder diesel would not put out heat until we got to 30mph. It did get 24 mpg and we cruised at 60mph and could get to 75 off a mountain. That front wheel drive in the 4 speed was fantastic in snow. It walked through things that four wheel drive struggled with and of course in 1982-83 four wheel drive was not common. We could stand up in the back and the van config was great with fold out couch in back and chairs that folded down into two beds. We were styling. Well when the LaSharo came along it was something. A bathroom and cooking area and supercharged. All that extra weight on that little 4 cylinder diesel. Just too heavy for small engine. In Europe yes but not here where we travel faster and go further in general.
