How to Measure 5th-Wheel Toy Hauler

Adco How to Measure 5th-Wheel Camper

To determine the proper fit, measure the length (front overhang 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 fifth-wheel toy hauler 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 5th Wheel Cover

This contour-fit cover helps keep your fifth-wheel toy hauler 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 and rear offer access to your toy hauler 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 toy hauler's surface. Additionally, the fabric beads water to eliminate pooling and ice build-up that can damage your toy hauler 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 fifth-wheel toy hauler 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

The cover features zippered panels on the passenger's side and rear so you can still access the interior of your toy hauler with the cover 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 toy hauler is in storage. The bag allows you to store the cover compactly in your vehicle or garage when not in use.

This cover arrived on time and I look forward to putting to the real test in a week or so when I install it. Thanks for your help, and the price was awesome. 724454

It has held up all the winter in NJ through some heavy winds. We have not removed it but I'm hoping it's as easy to take off as it was to put on. 606324

Great product, knowledgeable/very helpful customer service. However, wrong product was shipped resulting us a delay with our move departure date, for waiting on delivery of right product. Very frustrating. 546991

We only used the cover for 4 months during a mild winter and we have some wear at the rig corner locations and a couple of small tears. Otherwise it worked well. 711573

To help repair some of those minor tears and wear, Adco offers a Universal Patch Kit # 290-2093
Adco Universal RV Cover Patch Kit - 6 Colors
. This kit includes several patch options to help extend the life of your cover without using the covers warranty.

I make a point of shopping around online for my trailer supplies & needs, but I always end up ordering from Etrailer. They are my preference because they have a very good understanding of their products and applications, they have a good selection of products, and they go out of their way to be price competitive and accommodating during the calls. And the follow up after the product has been shipped and received to ensure customer satisfaction makes them my only choice. 700474

I do not recommend this product. Although I purchased this cover in Nov 2017, I did not take it out of the box and put it into use until Jan/Feb 2018. The cover did not hold up well at all. The material failed to maintain its integrity over the 8 months it was in use. Anywhere the material rubbed a protruding object on the RV, it wore a hole in the material, and the white Tyvek material on the roof cracked and tore apart at stress points. The materials used seemed to dry-rot very fast, when attempting to unsecure all the tie down straps, unbuckling them and pulling slack, the material would tear easily, it felt very similar to tearing a paper towel, instead of allowing slack to remove the cover. When I noticed the objects rubbing through the material, I called Adco and they sent me patches. Although this product was advertised to endure the elements, I would only recommend using this cover in conjunction with storage under a permanent structure/facility This product comes with a 3 Year Warranty, but did not last 8 months of use. Adco does not allow etrailer to handle the claims, and although I'd asked for a refund, Adco would only send me a replacement cover....anyone want to buy an RV cover cheap?? 584362

In general the cover served the purpose I bought it for - covering a 38ft toyhauler for winterization purposes. We did experience some tearing of the fabric on the two front corners by the front hydraulic jacks. Not re-enforced well on the corners but the cover did come with some repair material. The back cover allowed us to pull in and out our ATV's - it rolls up allowing the back door to be lowered. The straps that hold the cover up while accessing the door could have been placed better and with stronger velcro straps. In general for protection of the trailer and access to all the doors while covered it has worked for our situation. My toyhauler is a Road Warrior with a 10 ft garage. 579351

After watching the video a couple of times, installation was very straight foreward. It’s best to have a helper to help pull the cover in place and getting it somewhat square on the trailer. Just followed the instructions in the video as I started cinching it down and securing it to the rig. Feels like a very sturdy cover so it should last several years. My test will be the early spring wind storms here in New Mexico, hopefully it’s secured so that it doesn’t fly off to the next county. Very important to wrap the downspouts on your rig to prevent them from eventually tearing a hole in the cover. I wrapped mine with bubble wrap material and then taped the bubble wrap to hold it in place prior to unpacking my cover from the shipping box. After unpacking my box, I found 4 downspout covers in the contents of the box so will put them away until next year. Only time will tell from this point going foreward. 578562

Well, like some of the other reviews the rips started occurring. 3 of the cinch straps pulled loose from the fabric. Notified Adco and sent pictures of the issues and they agreed after a couple of days to replace the cover...Just give them a card number so they could charge me $XX shipping. And by the way there would not be any warranty on the replacement cover. I am very confident that the new cover is not going to work any better as it’s just exactly like the first cover. I certainly don’t recommend this cover due to the poor quality and for a company to not warranty their replacement parts says enough about the company. Paid a high dollar price for this cover and didn’t last quite a year. Shameful,

Great cover especially for the cost. Installed by myself with the trailers ladder and a 10ft that I have. I recommended it to the other 1400 members of the Genesis Supreme page for their trailers. Fast shipping and great follow up from etrailer. 508519

So just got this installed on a 2019 Forest River Cherokee Wolf Pack toy hauler 315Pack12. It fits great. A little slack on the top in the front, but otherwise looks good. We will see how it does over the winter in Central PA. The "rain gutter protectors" are a joke, not sure how they would ever stay on. I used foam pipe insulation and duct tape to protect the rain gutter spouts. The biggest thing I can say is that you MUST protect ever sharp edge on the camper, otherwise the movement from the wind will rip a hole in the cover very fast. This has been my learning curve with 2 other adco covers on tow behind rv's in the past. Fingers crossed, but I have had good experience with these covers. We will see how long it lasts. 728564

Donna R was very courteous, very calm & knows the ins & outs of products offered. It is obvious she is a key employee which any company would want. I've never met this person, I'm from Canada, but I can tell she catches on quick ! My advise to management would be to make sure Donna has a comfortable atmosphere at her work station & make sure she is happy with her current salary. I am glad to have dealt with you Donna. Have not tried rv cover yet, but is well packaged. Received unit on 13 july 2020. I'll certainly keep your info in my favorate list & may do business with you again. Thanks you 837436

Excellent. Was a bit worried because of our potential for high winds here. This cover has held up through 50+ mph winds. I will definitely be buying another one of these when the time comes 794104

It look great haven't used it yet, it will be a couple of weeks before we button up for the summer. 764893

- 290-34857

The overall product is ok. The only issues is durablilty of the product. In windy conditions the cover will find and snag any sharp objects and rip the cover which will need to be repaired. The cover does protect my rv very well. This is my 2nd winter with my rv and the cover is still working. I hope i can get 2 or 3 more season out of it before i need to replace 734226

Cover performed well. But, all sharp edges must be protected or they will wear through very quickly. We had most but not all edges prepared. Requires use of foam noodles and split tennis balls. Otherwise great cover for the $. 663378

- 290-34857

What can I say? Initial quality is is high as it gets. Install is straight forward. Included tyre guards are a plus but the real pleasant surprise is the included rain gutter protectors and ladder protector. I highly recommend this cover or its different sized counterparts. etrailer is super fast getting things to me as always. 577379

Two rips out of the box and then two larger rips which are now holes from rubber on the trailer. Clearly won’t last. 572217

Was easy to cover the RV, it had the necessary straps to tighten the material around the RV. Once applied it was easy to unzip the cover for easy access to the RV's doors. Product was well made. 568825

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

  • Storage Cover for a Keystone Outback 324CG in a Hot, Dry, and Sunny Climate
    If your Keystone Outback 324CG happens to be a 2017 model that is 36 feet, 10 inches long then the best option is Adco all-climate cover # 290-34876. This cover will protect the trailer from UV rays from the sun and also protects against those hot winds down in the great city of San Antonio, Texas. It also comes with 4 tire covers since the main cover will likely not completely cover the tires. If your Outback is longer or shorter than the 33'7" to 37' this cover fits let me know and...

  • Can I Get the Adco RV Cover without Tyre Gards?
    The Adco RV Cover w/ Tyre Gards for 5th Wheel Trailer - All-Climate + Wind - Tyvek - 40' Long # 290-34857 doesn't come without the tire covers. The Tyre Guards are sold separately but they do not sell any cover without the Tyre Gards. The manufacturer basically adds the UV tire protection as a bonus, as they would otherwise cost you the additional money.
