Dometic Power Awning Replacement Fabric, 17', Onyx

When your RV's power awning fabric starts to crack, fade, or split along a seam, you don't need to replace the whole awning. You need the fabric. This is the genuine Dometic replacement fabric for a 17-foot power patio awning, cut for an 8-foot extension, in the Onyx pattern with a black vinyl weathershield. It reuses your existing roller tube, arms, and motor, so you're swapping the vinyl and getting back under shade for a fraction of the cost of a full awning.

The Onyx pattern is a deep charcoal fade that reads almost black from a distance and warms up a little toward the edge. It pairs well with darker coach paint and modern trim, and it hides road grime and mildew streaks better than a light color does. The black vinyl weathershield is the protective outer wrap, the part that faces the weather when the awning is rolled up tight against the coach. That's the panel that takes the sun and rain when you're parked or rolling down the highway, so it's built to shrug that off.

This is the LED version. On Dometic power awnings equipped with the front-rail LED light strip, the fabric has to be the matching cut so everything lines up when the awning extends. "With LED" tells you this is that version. The light strip itself lives on the awning's lead rail, not in the fabric, so it stays right on your unit. You're replacing the vinyl only.

One-piece construction matters on a long awning. A single panel of vinyl means there's no center seam to wick water, leak, or split after a few seasons in the sun, and the center seam is usually where older awning fabric gives out first. Vinyl is the workhorse of RV awning fabric. It sheds rain, blocks the direct sun off your patio, and wipes clean with soap and water. Keep it dry before you roll it up and it'll go years without mildew.

A word on sizing. Awning fabric is measured by the nominal length of the awning, not the exact width of the vinyl, which is cut a little shorter to fit between the arms. This is the 17-foot size with an 8-foot extension, so it projects about eight feet out from the coach when it's fully open. Before you order, confirm the nominal size stamped on your awning or listed in your coach paperwork, and check that your awning is the power (electric) style with the LED strip. If you've got a manual pull-out awning or a different length, this is the wrong fabric for it.

Swapping awning fabric is a real job, but it's a driveway job, not a shop job. Grab a second set of hands and set aside an hour or two. The short version: with the awning extended, you relieve the spring tension on the roller, slide the old fabric out of the roller channel and the lead-rail channel, then feed the new fabric in the same way and re-tension. Take your time on the tension step and keep the fabric square as it feeds. Plenty of owners knock this out in an afternoon with basic tools. If spring tension makes you nervous, any RV shop can install it in short order.

Be clear on what this is. It's replacement fabric only. It's not a complete awning, it doesn't include the roller, arms, motor, or the LED strip, and it isn't a universal one-size sheet. It's the correct Onyx vinyl for a 17-foot Dometic power awning. If that's what's on your coach and the vinyl is done, this gets you back under shade without paying for a whole new awning.

It ships rolled in a protective tube, so the vinyl arrives without creases or hard fold marks. Let it relax and warm up before you install it, especially in cold weather, and it'll feed into the channels a lot easier. After that, a little care goes a long way. Rinse off sap, pollen, and bird mess before it sets, avoid rolling it up soaking wet, and retract it in wind and before you leave the site. Treated right, a vinyl awning fabric like this holds its color and its water resistance for years of camping seasons.
