Just a tip about moth balls. I wouldn't use them in an RV or even a house for that matter.
They cause lung irritation/problems when inhaled and serious damage to children if they inhale it.
An RV is VERY small the smell and chemical irritants of those balls will just about kill you. Not to mention you will NEVER get the smell or fumes ever out of the RV.
small snip it.
../"mothballs contains 396 grams of naphthalene, which is sufficient to raise the average residential indoor air concentration to approximately 200 micrograms per cubic meter over a period of 1 year, though in small homes or apartments this would be expected to be much higher. Exposures of this magnitude are commensurate with industrial exposures to ... jet fuels.”
Babies are especially vulnerable because their bodies are less able to clear naphthalene byproducts formed in blood.
they’re a health hazard for kids for several reasons. Naphthalene exposure can cause red blood cells to break apart, a condition known as hemolytic anemia..." Just saying.
