How to Measure Your Class C RV

How to Measure Your Class C RV

To determine the proper fit, measure the length (front bumper to rear bumper including spare tire or ladder, where applicable) and sidewall height (undercarriage to the top of the natural roof line). This cover is designed to accommodate rooftop accessories such as AC units and vents.

Choose Cover by Climate

Adco Climate Map

The climate where you are storing your RV will help determine which cover to choose. This Tyvek All-Climate + Wind cover is designed for use in all climates located on the map above.

Adco Class C Cover

This contour-fit cover helps keep your Class C RV dry and well protected when not in use. It features a 3-layer DuPont Tyvek top and 3-layer polypropylene sides to protect against sun, rain, mold, and mildew in all climates. Elastic corners and a rope cinching system allows you to draw the cover in tight over your vehicle. Zippered panels on passenger's side offer access to your RV during storage. Includes 4 Tyre Gards to protect your vehicle's wheels when stored.

Fabric Guards Against Elements

Adco Class C Tyvek Cover

The top panel is constructed of triple-layer DuPont Tyvek fabric that is stronger and more UV resistant when compared to standard polypropylene covers. It blocks 99.8 of damaging UV rays while keeping the interior cool through infrared heat reflection. It also prevents 98 percent of dirt and dust particles from reaching the RVs surface. Additionally, the fabric beads water to eliminate pooling and ice build-up that can damage your RV or cover. And the material resists acid rain, bird droppings, tree sap, dirt, dust, and other forms of environmental pollution that cause black streaks.

The sides of the cover are made of a non-abrasive, triple-layer polypropylene. This high-performance, non-woven fabric is water resistant and breathable to prevent the growth of mold and mildew.

Air Vents Help Cover Breathe

Adco Class C Air Vents

Air vents on the sides allow air to escape the cover in moderate winds to prevent billowing. These built-in vents also help the cover breathe to prevent mold and mildew.

Straps and Elastic Corners Ensure Snug Fit

Adco Corner and Cinching System

The cover is designed to fit snugly over your Class C RV for a clean look and better protection from the elements. Elasticized corners grip your vehicle tightly, and they are reinforced to reduce wear and prevent tears and snags. Cinch ropes in front and back remove slack and reduce billowing.

Adco Strap and Buckles

Weighted straps with buckles run beneath your vehicle to secure the cover in place. The weighted ends allow you to easily toss the straps from one side of the vehicle to the other. Once buckled, the straps can be pulled tight to ensure the cover is securely fastened so it won't blow away with the wind.

Zippered Panels Offer Access

Adco Tyvek Side Panels

The cover features zippered panels on the passenger's side to allow access to the interior of your vehicle while the cover is installed.

Storage and Protection

Adco Class C accessories

A ladder cap, rain gutter spout protectors, 4 Tyre Gards, and a storage bag are included with the cover. Place the cap on top of your vehicle's ladder and the protectors over your rain gutter spouts to reduce wear on the cover. The Tyre Gards protect your wheels while RV is in storage. The bag allows you to store the cover compactly in your vehicle or garage when not in use.

Very smooth transaction, from placing the order to receiving. Thank you 645023

eTrailer I give 5 stars too. Best price I found on the Internet with quick shipping. This is my second 34813 cover. The first one I purchased used was around 5 years old sealed in the box. Motorhome is covered around 8 months of the year. I got close to three years before the Florida sun took its toll on the cover. Tyvex was starting to get very brittle and top seam came apart. The newer design elements are OK and will probably last through the warranty period. For me its worth the money to keep RV out of sun. Think I'll try silicon seam sealer on top stitching twice a year. 550484

Still holding up good. Think Adco could [] the new cinching straps on the four roof corners and instead fortify the rear bumper corners with an additional layer. This has been the first area to have holes on both covers Ive owned. The stitching has started unraveling near zipper for side door. Still worth having RV covered.

My cover has survived a very windy New England Winter with little wear. I had used pieces of gray pipe insulation to pad the gutter spouts, and snugged it down nice and tight. Yes that is snow, the snow arrived before I was ready for it. But making a snowball around the weight to throw the tie downs from side to side made it easier to find them in the green grass under my RV. It had several different events with winds of 50 to 60 mph to contend with, the worst it did was toss some snow buildup off the roof. I did have wear and tear at the exhaust pipe. Now I know to put a plastic flower pot over it, and I'll use a pair of larger flower pots on the rear bumper to prevent those friction locations too. Yes I'll buy one when this on finally wears out. The videos were helpful in putting it on and taking it off. I didn't try to put it in the bag provided. It is folded up in a 32 gal trash can with wheels because it is just easier to move around. 633107

Very fast. Thank you 892508

It was a nice looking cover and fit well. It did what I bought it for which was to protect the coach from the elements, especially the sun. It was difficult for one person to install and remove the cover. Unfortunately a neighborhood dog did not like the cover and shredded it one night. I woke up to ribbons of the cover all over my yard. That convinced me to build a permanent RV port to protect it going forward. 828757

Excellent product. Fits perfect. etrailer is the only place to buy from, especially during COVID. 817487

It lasted a year with no problems. I cover the RV for winter and just removed it a week ago. Everything fine, and I am even learning to fold it! 797438

We LOVE our new RV cover. The price is great for the excellent quality! Easy to put on and looks good, too. Definitely giving this 5 stars. :-) 762869

It has not worn very well. Multiple patches needed and the patches do not stick very well. It has protected the RV, but the fabric abraded easily. 729150

I purchased the 26’ Class C cover for my Thor Vegas. My RV’s actual number to number length is 26’6”, so I probably could have gone up to the 34814 size. The final corner was tight getting the cover over the sides, but it does fit snugly and cinched down fine. We’ve had two big wind storms already and there’s no sign of any part of the cover loosening. I can get inside the RV by unzipping 3 zippers (two vertical, one horizontal along the bottom). The cover appears very durable. The ADCO cover came with grey wheel covers, but I already had covers on the wheels before purchasing the RV cover. I’m glad to have the RV covered this winter. 727582

- 290-34813

The cover worked good but I had it too tight and a small hole occurred by the ladder from windy conditions and I need to patch it. Make sure it's not too tight or protect areas to keep it from wearing, ladders, exhaust pipes or antennas. 702792

- 290-34813

I purchased this cover to provide protection to my 25ft Class "C", stored in Florida. I had it on and off twice, the longest duration 3 1/2 months. Having two people helps when installing and removing, it's a big cover. I'd like to say very good product, but the fabric chaffs easily. I put padding on large sharp areas (ends of the bumper) and tennis balls on small sharp things that stick out (awning roller ends, generator exhaust, roof gutter spouts). All those areas show wear with one tennis ball worn right thru the fabric and making an 8 inch tear. This was my first cover so I don't have anything to compare it to, but was hoping for better. 662222

I do think the zipper for the entry side should encompass the front passenger door also. 648020

Received the wrong product the first time. They Emailed a shipping label and I sent it back. Easily done. Ordered the correct product and 2 days later it was here. On top of that I am not even a prime member. Great product and customer support. Keep up the good work. 617610

- 290-34813

This is a good product for snow or rain. It fit nice and tight and strapped down easily. If used in a secluded place with no air forces it would be just fine. HOWEVER, it will not withstand winds of sustained 35-40 MPH with gusts 50-60 MPH or higher. It ripped out along the zippers first, then along the seams on the opening side. The rest stayed intact. I felt it useless to try to repair so it was removed and trashed. 597786

Review from a similar All-Climate Plus Wind in RV Covers

Shipping was super fast. Thanks everyone who had apart in helping me out with questions (Bryan). The box is big and I hope to install the cover as soon as the snow melts here in Minnesota. I've bought a few of this brand of cover before. They hold up for a few years if you keep them on tight and snugged down from the wind. Padded at the sharp corners. Thanks Dino 611241

The cover is working great. I dont expect it to last forever. The sun can destroy anything. Good price for the cover. Use extraa pull ties and bungees

    The Classic Accessories PolyPro cover you'd looked at, part # 052963793635 would be a fit, but for the best available protection against UV rays, dust and weather, I'd recommend the # 290-34813 from Adco. The cover fits motorhomes up to 26 feet long, and would work great for you. Tire covers are also included to protect your tires from UV rays during storage.
