I have a 2019 Miramar 37.1 and when I open some of the outside compartments there is a plastic odor inside of the storage area. Does anyone have this odor condition. It seems to be in the forward three compartments. Could it be the material that the tubs are made of or something else ? I bought new and the odor has been there since delivery.
As long as you're not getting a musty odor: my guess is that it's just the plastic that those compartments are made of.
But to be safe and sure: empty them out, and wipe them down with a disinfectant. Let them dry out, and then see if you still notice the odor.
So the smell has been there since purchase and delivery? You have contacted the dealer who sold this to you correct? If not, why not? I would think your first call would be to the dealership that sold this to you.
Originally there was a very slight leak from the propane hose going to the H/W heater that has a connection in one of the compartments. It was hard to differentiate the slight odor of propane in the compartment from the plastic odor . The hose was changed but the plastic smell is still there. I ran the furnace and shut the tank valve off to empty any propane in the line in case there was still a leak. Aired out the compartments and then closed them up. Still a plastic smell. Have tested the compartment with two different gas detectors but no alerts or positive reading for propane.
