Review on 🐜 BougeRV Stainless Steel Mesh Insect Screens for RV Furnace Vent and Water Heater - Premium Bug Screen Covers for RVs, Campers, and Trailers (3-Pack) by Will Jenkins

It was exactly as advertised but make sure you measure before ordering, they come in a variety of sizes. I've seen rigs that are too small, which defeats their purpose. Mine fits perfectly, I'm very satisfied. Must prevent creepy crawling and flying creatures from nesting and burrowing in the vents of my stove and water heater. Installation is easy even when bundled with the right installation tool. I think they are essential and honestly should have come with the campervan but. they don't buy them, it will save you in the future.
