A heavy-duty torsion spring, die-cast castings, and a secure rafter lock make it a smooth one-person setup that shades the whole patio side of your rig.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Dometic 8500 is the manual patio awning a lot of RVers end up wishing they'd bought the first time. This one measures 20 feet of roller length with an 8-foot extension, wrapped in Onyx double-sided vinyl behind a black vinyl weathershield and finished with black castings. It's a big awning built for full-size travel trailers and fifth wheels where you want real shade over the whole patio side, not just the door.\u003c\/p\u003e\n\u003cp\u003eHere's the honest part up front. The title says hardware must be purchased separately, and that matters. What ships is the awning assembly itself, the roller tube, the fabric, the arms, and the end castings. The mounting hardware that bolts to your rig, the brackets and the awning rail attachment kit, gets ordered separately based on your coach. If you're replacing an existing 8500 or a same-pattern Dometic manual awning, your current mounting points usually carry right over. If this is a first-time install, plan on sizing the mounting kit to your wall before you order.\u003c\/p\u003e\n\u003cp\u003eThe 8500 has been Dometic's workhorse manual for years, and the reason is the guts. The arms run a heavy-duty torsion spring assembly with self-lubricating bushings, so rolling it out and cranking it back stays smooth season after season. The end castings are die-cast, not stamped, which is what keeps the whole thing from getting sloppy after a few hundred cycles. One person can set it up. You pull it out with the strap, set the pitch, and lock the rafters.\u003c\/p\u003e\n\u003cp\u003eThat rafter lock system is the part people don't appreciate until they've used a cheaper awning. It stabilizes the arms and puts automatic tension on the fabric so it doesn't flap and drum every time the wind picks up. Dometic's PermaLoop pull strap keeps the fabric tensioned while you move the arms between the pivot and carport positions, so you're not fighting a loose canopy mid-adjustment. Little stuff, but it's the difference between a two-minute setup and a wrestling match.\u003c\/p\u003e\n\u003cp\u003eThe fabric itself is a 4-ply laminated polyester-reinforced vinyl. Double-sided, so the Onyx pattern reads clean whether you're looking up at it from your chair or someone's looking at your rig from across the lot. Vinyl handles UV and it's scratch resistant, and the panel is cut with an automatic rain shed so water runs off one side instead of pooling in the middle and turning into a sag. Pitch one arm a touch lower and the runoff does the rest.\u003c\/p\u003e\n\u003cp\u003eThe black vinyl weathershield is the cover that wraps the rolled-up fabric when the awning is stowed for travel. It keeps road grime, UV, and weather off the canopy so the fabric lasts, and the black shield with black castings gives you that blacked-out look that pairs well with darker exterior graphics and trim. Onyx is a safe, sharp color choice that hides dirt better than the lighter linen fades.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Owners of larger travel trailers, fifth wheels, and toy haulers with a 20-foot-plus patio wall who want a full-length manual awning and don't need power. Manual is simpler, there's less to break, and there's no motor or wind sensor to fail. If you park seasonally or you're the type who cranks the awning in every time you leave the site, a manual 8500 is honestly the sweet spot. If you want push-button convenience or automatic wind retraction, that's a different Dometic model.\u003c\/p\u003e\n\u003cp\u003eA couple of straight-shooter notes. Twenty feet is a lot of awning, so this is a two-ladder job to hang even though one person can operate it once it's mounted. Always crank it in during storms and before you tow, because no awning likes highway wind or a gust front. And double-check your mounting-hardware order against your coach's wall height and rail type before it ships, because getting the awning but not the right brackets is the most common hiccup we see on these.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e20-foot roller length with an 8-foot extension covers a full patio wall on larger trailers and fifth wheels.\u003c\/li\u003e\n  \u003cli\u003eManual operation, one person can roll it out, set the pitch, and lock the rafters in about two minutes.\u003c\/li\u003e\n  \u003cli\u003e4-ply laminated polyester-reinforced vinyl canopy, double-sided so the Onyx pattern looks clean from both sides.\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty torsion spring assembly with self-lubricating bushings keeps the arms smooth cycle after cycle.\u003c\/li\u003e\n  \u003cli\u003eDie-cast end castings resist the slop and rattle that stamped hardware develops over time.\u003c\/li\u003e\n  \u003cli\u003eSecure rafter lock system adds automatic fabric tension so the canopy won't flap and drum in the wind.\u003c\/li\u003e\n  \u003cli\u003ePermaLoop pull strap holds tension while you move the arms between pivot and carport positions.\u003c\/li\u003e\n  \u003cli\u003eAutomatic rain shed runs water off one side instead of letting it pool in the center.\u003c\/li\u003e\n  \u003cli\u003eScratch-resistant vinyl with UV protection stands up to sun and road grime.\u003c\/li\u003e\n  \u003cli\u003eBlack vinyl weathershield wraps the rolled fabric for travel and gives a blacked-out look with the black castings.\u003c\/li\u003e\n  \u003cli\u003eMounting hardware sold separately so you can match the brackets to your exact coach.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Dometic reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat's the actual size of this awning?\u003c\/summary\u003e\n    \u003cp\u003eThe roller is 20 feet long and it extends 8 feet out from your rig.
