Adco AquaShed Cover Installed

You're worried about your Class B van getting wet and dirty in storage before your next camping trip. Whether you're storing your van in the rainy northwest, snowy north, or humid south, this weather-resistant cover is designed for use in extremely wet climates so your van will be protected. When you keep your van covered, you are less likely to need to wash and wax it in between trips. And if you want to trade your van in for a newer model later down the road, this cover will help maintain that resale value.


Adco AquaShed Material

The 3-ply SFS AquaShed top panel reduces moisture buildup that can damage your van over time. It also beads water when it rains to stop it from pooling or freezing, which eliminate the black streaks and corrosion you tend to see on the sides and roof of your van. And when the rain stops, the fabric dries quickly to minimize the development of mold and mildew. The top panel blocks the roof of your van from mild sunlight as well, protecting the cover from cracking and fading.


How to Measure Your Class B Camper Van


How to Measure Class B

To determine if this cover will work for you, measure the overall length of your van from the front bumper to the rear bumper. Make sure you're accounting for any spare tire carriers and ladders on the back, but not the hitch. Then measure the overall height from the ground to the top of the van. Do not include any AC units, vents, or antennas in your height measurement, as the cover is already designed to accommodate them.


Securing the Cover onto Your Camper Van


Adco AquaShed Cover Straps

The included ladder cap helps prevent the cover from splitting on that area of the van so install it first. Then unroll the cover and carefully spread it evenly around your van, making sure you don't pull too hard and tear the fabric. Once the cover is in place, wrap the elasticized hem on the cover around the bottom corners of your van to remove any excess slack in the material. Thread the included cinch rope through the built-in grommets on the cover and pull on them until the cover fits snugly around the contours of your van. And then toss the weighted straps underneath your van to the other side and buckle them together, which keeps the cover secure and prevents it from flapping in the wind and damaging the paint job.

My wife and I just installed it so I can’t speak to longevity.
We are in our 70s so up on ladders to drape it over was a bit dicey
Cover seems to fit fine.
Recommended instructions with photo would be helpful.

Thanks for the review Brent! We can definitely understand the challenges during installs, especially when height is involved. We appreciate the suggestion about adding photos to the instructions, that's helpful feedback. We'd love to know how the cover holds up later on. Thanks again for sharing your experience and we appreciate you choosing etrailer!

First time I took a chance on a winter cover for my Thor Four Winds 29G Class C RV and the 26-29 foot cover fit like a glove. The video was very helpful. I wasn't really sure how long it might take putting it on by myself, but it was only maybe 90 minutes total. Also, because it was a permanent camping site with gravel and not smooth concrete or blacktop, I wasn't sure how easy getting the straps under the RV would be; but the included weights usually made it under after only a couple of tries. I think the zipper access to inside the camper will be very useful as well when checking on the RV over the winter and starting the engine periodically. Great product so far!

That is great to hear, and it looks great on the Thor! I am glad you were able to get it on yourself with the help of our video. I agree the weights add a sense of ease to the install. What area do you have the Thor in, does it have some gnarly winters?

This size fits the 19ERD GulfStream Vintage Cruiser. I had another larger size (made by another company) which was too big - couldn’t cinch it up enough to keep it from catching the wind.

I hope that it will hold up!

I am glad it fit well, and I am sure it will keep that GulfStream protected. I always like to suggest if possible making sure to park somewhere that will get the least amount of wind. That always helps with longevity if possible.

by:
Easy to install and fits well (the installation video from ADCO is beneficial). Many useful features included, etrailer price is competitive, free shipping was 2 days, and customer support is excellent. I just covered my RV, therefore have no comment on product quality/longevity at this time.

I just installed the ADCO trailer cover on my 2023 Rockwood GeoPro G19FDS.
The cover fits great and was easy to install.
The cover quality was excellent.

The cover is working out great. Seams are good and the material is holding up well. I definitely will buy this again in the future.

After a year of the Florida weather, I will say it has been nice having the cover. I ordered the larger version to fit my V-nose 7x16 extended height trailer. It sucks to cover it by yourself, but if you have a method to the madness, it isn't as bad as it could be. I would've liked to see more reinforcement at the corners to avoid tears and punctures. It could also use a better system to tighten it down around the middle of the trailer. The belly ( under the trailer ) clips have held up and are fairly easy to tighten down to avoid flapping around. It does have some wear through areas which I will use heavy duty tape to try and slow down the damage. All in all, it has done its job to this point, and if you break down the cost per month to date, it is doing ok for the price point.

Measure , measure, measure your trailer before purchasing. I thought I had a 6x10 trailer and it was actually larger than that when measured the outside. Result was buying too small of a cover and had to return it. Great News though, there was no hassle and no issue with returning it. 5 stars is because they were so helpful with fixing my “assumption”. The cover is fairly light (14 lbs) and easy to handle.

Thanks for your review, Dennis! Your advice to measure first is spot on, and we're glad our team was able to help get things sorted out when the cover turned out to be too small. It's great to hear the exchange process was hassle-free and that you found the cover lightweight and easy to handle. We appreciate you sharing your experience, and we're happy we could help find the right fit for your trailer!

by:
The cover worked well, but, as with all covers, is easily snagged and ripped. In my case it was on a sharp corner of a solar panel. I was able to pad all the sharp corners, and sew up the rip. This year the trailer will be in a new garage, so no need for a cover.
by:
This is my second one. The cover fits great looks great but only lasted one year before it shredded apart. But for the price it’s better than paying for a polish detail. Thanks for the fast shipping
by:
I think that the cover is a great cover and I would recommend it to customers who is interested in getting a well built cover that will hold up the weather.

Glad to hear it, thanks for the picture!

The lawn mower cover is doing great - no issues. However, the horse trailer cover failed after about eight months. It developed a tear on the trailer roof edge, which I patched with the included patch. And patched the patch with duct tape. That lasted about a week, and the wind tore a long slit along the trailer roof, causing one side to fall to the ground. I had to cut it off in pieces to remove. The roof portion was thin and almost translucent. The winds here are intermittent and less than 20 mph, which I don’t think is excessive. So I will not buy this product again and wouldn’t recommend it. For about the same cost I can have my trailer professionally detailed to preserve the paint.
by:
I would have liked the top portion to be made with more durable material. The Velcro strips aren’t high enough to hold the rolled up portion by the door so the soreness and closes easily. And the bottom of the zipper section should be continuous all the way around. It makes the cover more likely to blow around in the wind if the zippered section is rolled up. Just not as durable all around as my previous ADCO cover. But it will have to do for now. Hoping it lasts 5 years.

Glad to we had the right fit for you Dennis! What kind of horses are you hauling around, and where are you hauling them to? I used to show western when I was a kid, would love to have some of my own someday =)

I have ordered many times from etrailer and never been disappointed. Quality products, fair prices, fast shipping, and most importantly exceptional customer service, which is rare these days.
by:
As usual excellent customer service and delivery of my rv cover. We received the cover on time and once we close up the damper for the winter we look forward to protect it with this cover.
by:
The product arrived in a timely matter, it's fits well on our motorhome. Too early to comment further on this cover, however this is our second cover we have purchased from this same company and it's a great product and we were very happy with it. We probably could have with one for year before replacing, we had it for four years.
by:
Currently waiting on an RV detail before installing but the cover this is replacing did the job for us. The purchase and delivery was quick and easy. Ansley at e-Trailer was great and super helpful. Thank again e-Trailer!

I like the cover and the fit. Installing can be a bit precarious so take your time and be safe. I would warn others to thoroughly inspect their trailer prior to installing to protect against “all” possible tear locations such as ladder rungs, solar panel corners, AC cover corners, antennas, etc. and protect them from wear. During the first use approx. 4 months I developed 3 or 4 wear tears due to wind and weather. We’ll be repairing the tears and reinforcing those areas along with strategically placed “pool noodles” and foam pipe insulation in those spots that might wear through. Previous covers I’d purchased had a thicker white top that really helped with this issue but apparently is no longer available through e-Trailer. I would now rate this cover at 3.5 and will probably be looking into a more substantial cover.

@David Thanks for your feedback a year later. Your recommendation to use some pool noodles and anything else to protect corners and other hot spots for rips or tears is a great suggestion. We often will suggest to use pool noodles as well. I am sorry to hear that your cover is already ripping. That's definitely not something you should be experiencing. You do have a 2-year warranty on the cover. It may be work reaching out to them to see if they will replace your order. 1(800)541-2326 option 2.

As long as it holds up, doesn’t leak water, or damage my finish I don’t think that there could be a better product. The instructions were easy to follow and with two people the installation was fairly painless.

Cover on camper for 3 months. Ripped in a couple different places. Terrible fabric!

I am really pleased with the quality and there a lot of hooks and elastic to secure the cover. Shipping was fast also. Thank you etrailer.
by:
Trailer cover fits my Sundowner slant perfectly. It seems to be very well made. Etrailer had the best price and my cover was delivered in 48 hours. Would definately buy from them again.

  • Recommended RV Cover for a 2024 Ram ProMaster with a Rear Spare Tire Carrier
    Hey Stephen. For your Ram Promaster with the additional spare, I recommend the Adco SFS AquaShed RV Cover for Class B Camper Vans up to 21' Long # 290-12230. This is a Class B RV cover that will work with campers up to 21'. The full dimensions are 21'8" long x 7' wide x 8' tall. I recommend taking some measurements to ensure you have a fit. If you find that your measurements are a tad less, this cover comes with cinch ropes and underbody straps to take up any excess you may have. Do...

  • What Does Bubble Top Refer to For Class B Motorhome Storage Cover
    The bubble top height mentioned in the storage covers for Class B motorhomes like the part # 290-12220 that you referenced is referring to the height of the camper above the standard height of the van. So you could measure from the roof line of your van to top of camper and if it's 24 inches this would fit. If it's a 36 inch bubble top you'd then want the part # 290-12230. An AC unit would not need to be factored in as well.

  • Is The Classic Accessories Deluxe PolyPro III Heavy-Duty Cover A Fit For A 2022 Winnebago Revel

  • Storage Cover Which Fits a 2023 Ford Transit Cargo Van With Medium Roof and 19-1/2' Length
    The Adco SFS AquaShed RV Cover # 290-12230 is going to be the best fitting cover for your 2023 Ford Transit with the medium roof and the 19-1/2' overall length. The Classic Accessories # CA80104 you found is for vans at least 20' in length which means you will have some slack in the fit which leads to winds easily damaging the cover.
