Yeah just to save a few bucks they don't put an outside access door on. Lucky my 2005 still has it. For minor problems the furnace has to be removed and bench tested. While with a door you can leave everything in place and able to remove the main components.
The RV industry getting poorer by the day. Yes with a quick look everything looks nice and shiny but behind the shine the workmanship is poor.
You can order the door and everything needed from Atco.
