RV Repair: heater core replacement, heater core replacement, class a motorhome

Question
I own a 1996 allegro bay class A motorhome on a Ford chassie. How does the heater core come out of this type of truck chassie ? Through the front or through the inside?    Thanks RJL

Answer
What brand and model furnace is it? Most come through the front but I cannot find specs on the furnace for your MH. You may get the answer by emailing Tiffin. service@tiffinmotorhomes.com

I could not answer your last post because of problems with the form, so I will answer on this one. I cannot help with the cab heater core. You will need to post that with another forum.
