Why Every RVer Needs an RV Carbon Monoxide Detector

An RV carbon monoxide detector is an important safety and maintenance tool for your RV. Since it can help prevent a dangerous situation, it’s a must-have safety feature.

  1. Hi, thanks for this article. I like the fact that the First Alert has smoke detection, too. But if you’re cooking outside the van, and the slider door is open, isn’t the smoke from cooking likely to set off the detector?
