We had a LeSharo in our family - brand new around this time (1987ish.) I was middle-school age, and I clearly remember my aunt and uncle picking this up new and how much they loved it (at first.) Their LeSharo had the Renault diesel engine with FWD and manual trans. (I purchased my first RV in 1996 so I was a bit behind them :)
The box portion of their unit was fantastic. Very well thought out by Winnebago who clearly had a lot of experience in this area. The expanding bathroom was a very good idea. The floor plan was very efficient. The appliances and fittings are all mid 80s RV standard; thoroughly de-bugged with no major glaring issues beyond any other RV from this era.
The LeSharo issues I'm aware of were all due to the chassis, and the issues were MANY. Anyone looking at a LeSharo should do some research in this area. I know there are now options to swap out the horrifying Renault drivetrain with something less apocalyptic. If you could put a reliable drivetrain up front, and replace the rear bearings with parts made from something other than warm chocolate and wax; you would have a fantastic RV.
