AquaShed Cover Installed

You're worried about your horse trailer getting wet and dirty in storage before you need to transport your horses again. Whether you're storing your trailer in the rainy northwest, snowy north, or humid south, this weather-resistant cover is designed for use in extremely wet climates so your trailer will be protected. When you keep your trailer covered, you are less likely to need to wash and wax it in between trips. And if you want to trade your trailer 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 trailer 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 trailer. 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 trailer from mild sunlight as well, protecting the cover from cracking and fading.

How to Measure Your Horse Trailer

Measuring a Horse Trailer

To determine if this cover will work for you, measure the overall length of your trailer from the very front to the rear bumper, making sure you're accounting for any gear on the back. The cover isn't meant to fit over the kingpin of your trailer, so don't include it in your measurements. Then measure the overall height from the bottom of the trailer to the top. 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 Trailer

Adco AquaShed Straps

First unroll the cover and carefully spread it evenly around your trailer, 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 trailer to remove any excess slack in the material. Attach the included cinch rope and pull on them until the cover fits snugly around the contours of your trailer. And then toss the weighted straps underneath your trailer 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.

Adco AquaShed Zippered Access Door

And if you need to grab supplies, you can use the zippered panel on the passenger's side to easily access the interior of your horse trailer without having to completely remove the cover. You can also unzip the entire panel on the back of the trailer so you can open the tack door and load and unload gear.

Throw this storage cover over your horse trailer to protect it from rain and snow while you're storing it in between trips. Cover wraps around the bottom corners of your trailer and secures with integrated straps so it won't flap in the wind.


This gooseneck trailer cover was delivered quickly. The instructions were simple and helpful. The cover went on with all straps in place in about 15 minutes without needing a second person to assist.


Excellent fit and great reinforcement where it’s needed most.


Cover is very well made. Stitching and all buckles appear to be strong, as well as the tie down ears for the rope (provided) to pull out any slack. Once you get it going, it fits like a glove. I put it on myself, with the help of a ladder, and it took about 30 minutes. Very satisfied!!


The cover does it’s job. There were three places where it has already ripped in only a year. One place was my fault but difficult to prevent. It ripped where the drip tray ended. I had to tape some cardboard over the edge to prevent further damage. Be sure to cover all pointy edges. Which it does say that in installation directions but the drip tray isn’t “sharp” in my opinion but it was definitely enough of an edge to cause a hole. The other two were at rounded corners and should not have ripped. They were at a corner of the trailer and a running board and there was a part of the cover stretched to turn a corner. I haven’t reinstalled for the year but I am hoping I can repair the damage and reinforce the corners to use it again.

The Adco Cover Part # 290-46012 comes with a 2-year warranty. I will have Customer Service reach out to you.


The cover easily fit over my 26 foot goose neck (V-nose) enclosed car carrier trailer (even though it is made for a conventional horse trailer). The cover is very good quality and has already stood up to several thunder storms. Highly recommend this product.


I love this cover however it took almost an hour to put it on my trailer because I lived in the very windy desert so the wind was throwing it all over the place and. It came with no instructions on how to best get it on which would have been very helpful. I left it on my trailer for about 3 months in the summer/fall and considering the wind and sun it held up well. It got a few rips because the fabric isn't very thick. Overall I am glad I made the purchase but there are some areas for improvement of the design that could make it easier to put on and the fabric could be a tad bit thicker.


I received my order in a very short amount of time and am very pleased with the customer service. I was emailed when it shipped and again when it was received at the post office. I was able to put the cover on my trailer my myself in under 25 minutes. It was easy and fits the trailer nicely.The cover seems very well made:)


This cover has kept my trailer clean and dry over even our severe winter weather and so far the wind has not destroyed it as some of the other covers I have bought . So glad I found one !


Product arrived on time Fits my gooseneck perfect Easy to order and they offer lots of information for you to decide what works best


A very good cover easy to install and stores well this is the second one i bought higly recommended


Our cover just arrived just in time before the snow storm! We will watch how it will hold up through the upstate NY winter!







Without a doubt the best cover I've found for my e-Pro f19 travel trailer. It fits like a custom cover and the price was extremely reasonable. Best features: Four snug-fit corners (just like bed sheets); at least seven (?) tightening straps underneath the unit which means you can safely tighten and secure against brisk winds; two flaps/straps across both the front and back of trailer, again securing against wind. And the smallest pieces are my favorite ... two weighted straps that help you toss each of the straps underneath to the other side! Brilliant! You will see a "bump" along the back end of the RV and that's where the ladder is covered. The roof covering fits well but with enough room to accommodate the ladder, a/c, bathroom vent, and antennae. I've told my camping friend about this cover and this web site. I check here first when I need anything for my RV. Thank you!


After the money we spent on your trailer cover, thought it would if lasted longer than one year? Disappointed to say the least, learn from experience we guess.


Real easy to put on trailer.The cover does a great job of keeping debris off the camper and looks brand new still after 1 full year.


We ordered this cover awhile back and just put in on our Motorhome
for the winter. It was quite easy to put on and it looks like it good quality
and hope it does its job. We will know in the spring.


Very well made easy to put on the truck. Fits great on my GMC Sierra 2500hd crew cab .


After one year it has not held up at all. It falls apart in your hands. There are many holes from the wind and the sun has made it dry rotted. We were able to take it on and off twice and there would be one way to put it back on for a third time without it all just falling apart. To be fair we do live in the panhandle of Florida and do get a lot of sun and rain. We even put pool noodles around the rain gutters to try and prevent it cutting through the camper cover material, but after a while that’s exactly where the rips started from.


In the beginning, I was excited about the purchase. I knew the cover would keep my new trailer protected from the sun, etc. However, less than 3 months ago I noticed the material started to shed and become thinner on the roof. 2 months ago I noticed a small tear in front near the roof (no sharp edges there). Unfortunately the tear just got bigger and more disintegration of the roof. We took it off in preparing for the hurricane that came and in that process more of it just fell apart.
I am disappointed that the product only lasted a year. Now I need to figure out what to do to get a replacement. I prefer not to buy from your company knowing that the cover might only last a year.


Initially I was very satisfied with the cover. After 1 year there were some tears from the material flapping against the trailer body on the bottom edges. The 2 year anniversary just passed earlier this month (Oct 2023). This past weekend (Oct 22 2023) we had some mild winds, 15 - 20 mph. I noticed a tear had opened over the air vent (white plastic cover) in the dressing room area of the trailer. Later that morning, the entire cover roof ripped apart. See attached photos. I discovered that the trailer cover only has a two year warranty. I will start to look for another trailer cover manufacturer who uses better materials. Very disappointing.


My second purchase as the first, although 3 times as expensive and from a popular company, just didn't fit (sized in 3 or 4 foot increments). This cover from AuquaShed fit great and looks great. The material is somewhat easily damaged on sharp edges so extra care is needed to cover corners and trim edges.

The height and weight measurements are not as important as these covers are usually oversized in these areas to allow for a wider range of fits. The height of the air conditioner and antenna...
