Products were selected based on construction details (weave count, mil thickness), customer feedback about durability and fit, and features that matter to owners who store large vehicles outdoors or in unheated sheds. Read on to find the right tarp for roadside, marina, or backyard storage.

Frequently Asked Questions
How do I size a tarp for my RV or boat?
Measure from the lowest point on the roof to the ground (for RVs) or longest and widest points of the hull (for boats). Add at least 2–4 feet of overlap on all sides to allow for grommets and tie-downs. Choose a finished-size tarp when possible to ensure advertised dimensions match what you receive.
Should I use a waterproof tarp or a breathable cover?
Waterproof tarps prevent rain and snow entry but can trap moisture, which risks mildew. For long-term storage in damp climates, use a breathable cover or create airflow under a waterproof tarp with support poles or vents. For short-term or very wet conditions, a waterproof tarp with good ventilation points is preferable.
How can I prevent pooling and tears?
Prevent pooling by creating a ridge or using support poles to slope water off the tarp. Secure tarps with straps, bungee cords and additional tie points to minimize flapping. Use tarp clips or reinforce grommet areas with patches if you plan repeated installations to reduce tear risk at stress points.
