Durability: Durability and reliability are closely related concepts. You will benefit from a strong and long-lasting mr heater for rv for months and years to come.

Negative Reviews: Yes, we do take that into account as well! The goods with the majority of bad reviews are filtered out and disregarded when we choose the best-rated one on the market.
