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?

Check the specifications for your furnace, usually stuck to the side of the unit, but certainly available online. It will tell you the minimum return air duct size, which is often 80 square inches. With that information, you can probably block-off most of the return-air grill except for 8 x 10 inches (80 square inches). Most RV grills are far bigger than that. Also check the specifications for minimum clearance. You may have enough room to add some fiberglass insulation as sound absorbent in the cabinet where the furnace is installed.
