Very good point about it being a liquid cooled engine. However I assume there needs to be sufficient clearance above the engine as well. Excessive heat or fire hazard? Just don't want to create a larger problem by not thinking it through. May be analysis paralysis on my part
As for your question (@snrubel) I have not done the trunk/rear area yet but would be happy to comment when I get there. Probably several weeks off due to work and not wanting to work in a very cold garage.
Thanks
