Making an rv furnace quieter
Every rv furnace we have ever had was noisy. Has anyone done something to quiet there furnace. I have considered trying to wrap the blower area in insulation. Anyone had any luck?

The majority of the sound from our two furnaces comes from the large cold air returns. I lined the area behind the grills with a sound absorbent material, and even blocked off a section of the over sized grill with the same material, being careful to still exceed the manufacturer's required minimum opening area and minimize restricting air flow. The sound level reductions were significant, although I didn't take any before/after measurements.
