I hope your bus is a 'pusher-engine' job.

In Girt, a heater there would be right on top of the engine cover.


I assume the sheetmetal box is to prevent barbecued legs

Could you add some captions to your pix, please?
It's a mid mount engine, the sheet metal box sits on small legs, which keeps it of the carpet and to retain heat round the fire, that way it doesn't cool down as quickly as some others I've seen and it easy to pick up and put away in the mornings. Have handles on the flue pipes which make it easy to take apart when hot, it's set up that way so that all the heat is kept in the bus and not outside. Sorry about the captions though it spoke for itself.
Not just a pretty face are you
