kwkpr- Welcome to iRV2!!
I think you'll need to add some coach specific info (year, mfgr, model...) to attract the attention of folks w/your same coach and furnace system. Maybe also a fuller description of the furnace system you have, whether it ever worked on electric, etc... After that you will probably find a wealth of response.
FYI- using the UserCP feature at upper left you can add your RV data to your "signature" (see mine below- I never have to type that stuff each time I post, as the signature is automatic), along w/some useless, philosophical drivel if you so desire (again, note the editorial comment in my signature).
