Best DIY Bunk End Covers for Pop-Up RVs: Materials & Instructions

Bunk end covers (also called “bunk end caps” or “awning covers”) are essential for pop-up RVs. They protect your sleeping areas from rain, sun, and debris while adding insulation and privacy. Instead of paying top dollar for custom covers, you can create durable DIY versions with the right materials and a few straightforward steps.

Why Bunk End Covers Matter

Pop-up campers are more exposed to the elements than traditional RVs. Without protective covers, canvas ends can leak, collect dirt, and fade from UV exposure. Bunk end covers extend the life of your camper by shielding these areas from harsh conditions.

Best Materials for DIY Bunk End Covers

Marine Vinyl: Waterproof, UV-resistant, and highly durable. Perfect for long-term outdoor use.

Heavy-Duty Outdoor Canvas: Budget-friendly and breathable but needs water-repellent treatments.

Clear Marine Vinyl (Windows): Ideal for creating see-through sections to let in natural light without letting water in.

Tip: A combination of marine vinyl for durability and clear vinyl panels for light is a professional-grade DIY solution.

Step-by-Step DIY Instructions

Measure the Bunk Ends

Take exact measurements for length, width, and overhang areas. Add a few extra inches for hems and seams.

Cut the Fabric

Use sharp scissors or a rotary cutter.

Add Reinforcements

Sew or heat-seal hems with heavy-duty, UV-resistant thread. Consider adding grommets for secure tie-down points.

Install Fasteners

Use snaps, turn buttons, or Velcro to attach the cover to your RV frame for a tight, windproof fit.

Test and Adjust

Secure the cover and test it in different conditions (wind, rain) to ensure no water pools on the surface.

Maintenance Tips

Rinse off dirt and debris regularly.

Use mild soap and water for cleaning—avoid harsh chemicals.

Dry thoroughly before folding or storing.

Bottom Line

With marine vinyl and a few DIY tools, you can create bunk end covers that rival store-bought versions—at a fraction of the cost. These covers add years to your camper’s life while keeping your sleeping area dry, clean, and comfortable.
