Water Resistant RV Covers

Spring brings so much renewal and life for the outdoor lover. Flowers are in colorful bloom, creeks and rivers are rushing with abundant fish, and birds fill the trees with their musical melodies. Unfortunately, if you are an RV enthusiast, Spring can also mean water damage to your RV if you don’t own a CalMark Cover Water resistant RV Cover featuring  Sunbrella® Fabric. CalMark Covers, Leaders in Protective RV Covers since 1982, recommend checking your RV for water damage to see if you require a CalMark Cover Co Water resistant cover to protect your investment.

Investigate all cracks, seams, and moving parts. You will need to run your hands along every window seal, door jamb, and slide-out seam, both inside and outside. While some leakage is basically unavoidable without a cover, water damage can ruin your machinery, rendering your RV unusable. While camping, pay close attention to your clearance and avoid low-hanging branches at all costs. Those scratches in your paintwork might just be cosmetic, but over time, they could add up to a less effective roof and leaky ceiling. Never park your RV directly under trees, whose sticky sap will pull off layers of paint and surfacing.

A little about Sunbrella®

Sunbrella is founded on the belief that fabrics should be both beautiful and functional. They began in the 1960s with the challenge of creating an awning canvas with a substantially longer lifespan than cotton. Sunbrella has become widely adopted for shade structures, marine canvas and upholstery fabric for both outdoor and indoor applications.


Their textiles are made with close attention to design detail, and engineered with robust performance characteristics that provide resistance to fading and degradation from sunlight and chemical exposure. The fabric is tactile yet durable, has industry-leading environmental characteristics, is easy to care for and offers long life – wherever it’s used.


Each yard of Sunbrella performance fabric is a product of a global support team committed to producing only the most exceptional performance textiles you can buy.
