Frequently Asked Questions
What tarp thickness (mil) do I need for fall boat or RV storage?
For short-term or occasional covers, 5–8 mil tarps are lighter and easier to handle. For longer storage or rougher conditions (abrasion, salt spray, frequent wind), step up to 12 mil for better tear resistance and longevity.
How important is grommet spacing and edge reinforcement?
Very important. Closer grommet spacing (about every 18" vs. every 3') lets you add more tie-down points, which reduces wind stress and flapping. Reinforced edges or corner protectors keep straps from cutting through and extend tarp life.
Can I use these tarps as RV awning covers?
Yes—choose a tarp with the right size and UV protection, and plan for secure tie-downs so the tarp doesn't flap. For awnings, large-format 5–8 mil tarps are easier to drape, but add straps and windproofing if you expect storms.
