Will it fit my RV door?

It is sized for a 30 by 79 inch door opening, measured without the frame. Measure your opening before ordering, since a larger door will leave gaps at the edges.

Does the magnetic closure actually stay shut?

The magnets pull the panels together after you pass through, which works well in light wind. In strong gusts the lower corners can part, so some owners add a weight or extra fastener there.

Can I install it without drilling?

Yes. The cover attaches with hook-and-loop fasteners and adhesive tape, and nails are included only if you want a more permanent hold. Clean and dry the frame first so the adhesive grips.

How much does it help with heat and cold?

The cotton padding and waterproof backing slow drafts and radiant heat at the door, which helps most on single-pane RV doors. It is not a substitute for insulating the whole rig.

Can I leave it on while driving?

It is meant to stay in place while parked. Remove it or secure it firmly before travel, since wind at highway speed can pull the adhesive and stress the fabric.

Does it keep bugs out?

The panels close behind you, so it reduces insect entry compared with an open door. It is not a sealed screen, so gaps at the edges can still let small insects through.
