@safonerrva: If your RV skylight feels like a heater, you need to check this out. This insulator fits most standard 14"x22" vents and makes a huge difference. The reflective side helps keep the blazing sun out, while the thick foam helps stop heat transfer so your AC doesn't work overtime. Plus, the non-slip sides keep it locked in place, even in the shower. It’s a game-changer for staying comfortable on the road.#RVlife #safoner #RVmusthaves #RVaccessories #HeatBlocking
