Default High pitch whining from propane furnace

Hi all, I am back in search of more knowledge. I have a 1993 Hilo Classic model 26RD. Does anyone know what brand Furnace and or part numbers? I assume it is an Atwood furnace (Water heater is this brand). whining noise is almost metallic. Seems constant and is present at start up. I assume that I have a loose bearing on the blower motor and will need to replace.
Any thoughts?

I don't know the furnace brand, but I'm sure the blower is fairly easy to replace once you get to it and verify it's the source of the noise. Possibly, it could be lubricated, but that's just a wild guess. Once you get to the part, you'll be able to tell more.

I've never gotten into the furnace in my trailer, but I think you do so from the exhaust panel on the outside.
