Grumman P30 Cummins 4BT3.9
I just joined because this seems like a good connection to a lot of experience and information. I recently bought a minimally converted step van with a 4 cylinder Cummins diesel in it. It isn't a school bus, but all the conversion details will be the same except for not having to deal with a curved ceiling. I won't even be getting the van home until the snow melts in the spring.
I have some useful exprience having lived on a 35' boat for a couple years, lived in a converted (Boyertown) post office van for a while many years ago, and used school buses as moving vans a couple of times. I discovered that I could drive a school bus more hours in a day before getting tired than I could in a car. My guess is that it has to do with posture and better visibility.
I have also converted an off the lot, 12' X 32' storage building into comfortable living space with shower, composting toilet, wiring, and kitchen.
The step van was a bit of an impulse buy and I don't have any exerience with diesel engines. I guess the first steps will involve cleaning it out, servicing the vehicle, and doing enough driving to be convinced that the van is good enough to warrant the time and money to do a serious conversion. I think it is an 18' van and I have decided that I really don't want to drive a bigger rig.
Looking forward to the benefit of all the insights and experience I'm finding here.
