Excessive engine heat transfering to bedroom

Thanks for the comments. Mr. Mark, my shore cord 12v spool is located at the very rear drivers side of the coach, at about eye level, so it is in the engine bay and not insulated well enough.

I went to the coach today and looled under, over, and around everything. I didn't see any breaks, cracks or leaks. I spoke with a Cummins service center rep today and as I told my story I said I had never heard the radiator fan running...but that cant be because the engine would overheat. I'll start it up tomorrow and look at the fan. Thanks again.
