RV Undercoating Las Vegas

Most of what gets written about undercoating assumes a cold climate, where the real enemy is road salt eating through bare metal over a winter. That pitch does not describe Las Vegas, and this page will not pretend it does. There is no de-icing salt on these roads, and a coach that never leaves the valley is not fighting the corrosion problem a coach in a snowbelt state fights.

What the desert does instead is attack the coating and the hardware underneath it in its own way. Sustained heat radiating off asphalt and ultraviolet light reaching underneath the coach in a parking lot age an unprotected coating and harden exposed rubber and plastic components faster than a milder climate would. Fine desert dust works as an abrasive, wearing through a thin protective layer over time rather than sitting harmlessly on top of it. And while it is dry here most of the year, it is not dry every day: a monsoon downpour, a wash, or a wet drive still puts water onto whatever is underneath the coach, and bare metal with dust already worked into its surface has no barrier to stop that water from starting corrosion.

That is a real reason to coat the underside of a coach that lives in this climate. It is a smaller and different reason than a snowbelt shop would give, and it is stated that way on purpose.
