How to Choose the Right Tarp for RV Storage

RV owners face a particular set of challenges: large surface area, roof vents and AC units that catch wind, and months of sun or cold that can degrade materials. Your goal is to prevent water entry, reduce solar stress, and—critically—avoid trapping moisture against roof seals which leads to mildew. Start by prioritizing these factors: thickness (mil), reinforced edges and grommets, UV protection, and proper fit. A tarp that’s too thin will rip or be punctured; too heavy a tarp can be hard to tension and may pool water if not installed correctly. Look for rust-resistant or stainless grommets and reinforced corner patches—these reduce grommet failure when you tension the tarp around jacks or tie-down points.

Breathability is often overlooked. Few polyethylene tarps are truly breathable, so to prevent mildew you should select a tarp with a tight weave and install it with airflow in mind: leave small vents, prop the tarp off the RV roof with non-abrasive supports to allow air circulation, and use moisture absorbers or desiccant packs inside the RV during storage. If you can, choose double-sided or reflective finishes (silver/black or brown/silver) to reduce solar heat on sunny sides and slow material degradation.

Grommet spacing matters for RVs. Look for frequent grommet intervals (every 12–24 inches) so you can tension the cover without creating large unsupported spans that promote flapping and stress. Reinforced hems and sewn corner patches are essential to prevent tearing under wind load. Finally, check finished dimensions—many tarps shrink 3–5% after seaming—so buy slightly larger than your measured coverage area and plan attachment points accordingly.

What RV owners should look for:

• Thickness: 10–16 mil for long-term storage; 5 mil only for short-term or temporary use.
• Reinforced hems and corner patches to avoid grommet pull-out.
• Rust-resistant or stainless grommets; closer spacing for easier tensioning.
• UV-treated or reflective surfaces to reduce sun damage and heat buildup.
• Plan for airflow—lift points or vents to prevent trapped moisture and mildew.

Budget Tiers

Budget: 5 mil tarps are cheap and useful for short-term sheltering or covering non-critical items. Mid-Range: 10–16 mil tarps balance durability and weight—good choices for most RV owners who need seasonal storage. Premium: Heavier weaves, denser coatings and larger sizes offer the best protection for long winters or salty coastal storage, but expect heavier handling and storage bulk.
