Dometic 20' Power Patio Awning, Onyx Vinyl with LED Light Rail

This is the Dometic power patio awning that turns the side of your rig into shade in about fifteen seconds. Flip the switch and the 20-foot rail rolls out to an 8-foot extension, giving you a covered patio wherever you park. The fabric is Onyx vinyl in black, wrapped in a matching black vinyl weathershield, with black cast end caps and an LED light strip built right into the lead rail. It's a clean, dark look that hides road grime and campfire smoke a lot better than the old tan awnings.

Let's get the most important thing out of the way first, because it saves you a headache at checkout. This listing is the awning itself, meaning the roller tube, the Onyx vinyl fabric, the weathershield, and the LED lead rail. The mounting hardware, the powered arms, and the control switch kit are sold separately. Dometic packages it this way so RV builders and dealers can match the right arm hardware to the coach, but it means a DIY owner needs to order the matching Dometic power awning hardware kit and switch kit alongside this. If you're replacing a worn-out fabric and rail on an existing Dometic power awning, this is often the exact part you want. If you're starting from a bare wall, budget for the hardware too.

Why go electric? Anyone who's wrestled a manual awning in a gusty campground knows the answer. With a power awning you're not cranking, not reaching, not fighting a stuck ratchet. You hit the switch, the arms walk it out, and you're done. The 8-foot extension throws real shade over a camp chair, the grill, and the entry steps, so you can sit out a light drizzle or a hot afternoon without baking. And when a storm rolls in, you bring it in from the switch and stow the whole thing under the weathershield.

The LED strip in the lead rail is the upgrade people notice at night. It runs the length of the rail and throws a soft, even wash of light down over your patio space. No more clamp-on lights or string lights taped to the fabric. It wires through the same control setup as the awning motor, so you're powering it off the coach's 12-volt system. Great for late dinners, card games at the picnic table, or just finding the door after dark.

The Onyx vinyl fabric is built for the weather RVers actually see. Vinyl sheds water and wipes clean, so pollen, bird mess, and tree sap come off with a sponge and mild soap instead of soaking in. The black weathershield wraps the rolled-up fabric when it's stowed, which is what keeps a vinyl awning looking new season after season. UV and road spray are what kill an awning over time, and that cover is your first line of defense on travel days.

Fitment is straightforward once you know your numbers. The 20-foot measurement is the rail length, which is the mounting length along the side of the coach. The fabric rolls out to 8 feet of extension at full stretch. Measure the flat wall space on your RV before you order. You want the rail to fit cleanly above the entry door and windows without running into a slide-out or a corner molding. If you're between sizes, Dometic makes this same awning in other lengths, so match the rail to your wall, not the other way around.

Who's this for? Travel trailer, fifth wheel, and motorhome owners who want the convenience of a power awning with the cleaner look of the all-black Onyx setup and integrated LED lighting. RV techs and dealers replacing a sun-rotted fabric on an existing Dometic power awning. Anybody upgrading from a tired manual awning who's ready to stop cranking. It ships in a carton, and because it's a long roller assembly, plan on a two-person lift to get it up on the brackets.

One honest note before you buy. Because the hardware and switch kit ship separately, double-check that you're ordering the matching Dometic power awning arm hardware and control switch for your coach. Get those three pieces right and you've got a complete, great-looking power awning. We're happy to help you sort out which hardware kit pairs with this fabric and rail if you're not sure.
