Furnace Whine 2000 Tiffin Allegro Bus 37m 300 hp cat

I have a front furnace whine on my 2000 Tiffin Allegro Bus m37 300 hp cat.

Sometimes I can go outside and hit the side of the bus and it will stop but it only quits for a short time...

I am having a horrible time figuring out how to access it. Inside the bus there is an oversized vent that I can remove but it only gives a little view of one side of the furnace. The floor has been replaced with wood flooring. Underneath it appears to be in a welded box. In the front, on the side of the bus, there is no access handle to open the bay....

I would love to get access, clean everything up, determine the cause of the whine and fix it....

I am very new to this world and want to learn all I can by dealing with issues as they arise, not afraid of hard work but I need access...

Can anyone offer any help??

Also, I would be glad to add pictures to show you but I do not know how to add pictures on this forum...

RVs have problems due to lack of use
Furnace fan bearings dry out from lack of use and the fans squeal
I've never seen a RV furnace that didn't have an exterior access door
There are a number of components that can fail in furnaces' besides the fan ... sail switch, ignitor board, ignitor, etc
Mine fan started to squeal. I could have replaced the fan but I knew that I would continue to replace the other components
You can buy a new "core" for about $400. A fan part costs $150. by the time you replace all the parts that fail, you'll have more in it than a core.
I recommend you buy a core, that will replace everything but the housing
It literally took me 30 minutes to replace the entire core and I effectively had a new furnace.

Thank you for the sound advice.....

I have got to figure out how to get to this furnace...

I can't do anything until I gain access....

I'm thinking the bay door (no bay just covers the furnace) must be screwed on some how.....

I've got to spend more time under there to figure it out...
