Loud noise coming from furnace on new camper

[Average camper]

My issue with my suburban heater is that the entire housing is plastic. I'll continue to dig into this deeper and see if I can come up with either the cause or the corrective measure. Thanks for getting back.

Can't believe its all plastic and the motor is just set in there and not secured.

I've had a bunch of R/V furnaces apart.
I have never seen the inside of a R/V furnace where the motor isn't secured. If yours is not, that's either something new or something wrong.
