Adco Olefin Installed

Summer is over, and you're worried about your fifth-wheel toy hauler getting dirty and damaged in storage during high winds, snow flurries, and spring thunderstorms. Whether you're storing your fifth wheel in the sunny south, rainy northwest, or snowy north, this heavy-duty cover is designed to protect your fifth wheel in any climate. When you keep your fifth wheel covered during the winter, you are less likely to need to wash and wax it at the start of the camping season. And if you want to trade your fifth wheel in for a newer model later down the road, this cover will help maintain that resale value.

The durable, high-density Olefin top panel won't crack or fade when exposed to harmful UV rays and won't let dirt and dust particles cake onto the surface of your fifth wheel. It also beads water when it rains to eliminate the black streaks and corrosion you tend to see on the sides and roof of your fifth wheel.

How to Measure Your Fifth-Wheel Toy Hauler

Adco How to Measure 5th Wheel Toy Hauler

To determine if this cover will work for you, measure the overall length of your fifth wheel from the very front to the rear bumper, making sure you're accounting for any spare tire carriers and ladders on the back. The cover isn't meant to fit over the kingpin of your fifth wheel, so don't include those in your measurements. Then measure the overall height from the bottom of the chassis to the top of your fifth wheel. 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 Fifth-Wheel Toy Hauler

Adco Olefin Securing with Integrated Straps

The included ladder cap and rain gutter covers help prevent the cover from splitting on those areas of the fifth wheel, so install those first. Then unroll the cover and carefully spread it evenly around your fifth wheel, making sure you don't pull too hard and tear the fabric. The cover is labeled with "front" and "rear" to help you position the cover correctly on your RV.

Once the cover is in place, pull on the cinch ropes on the front and the rear until the cover fits snugly around the contours of your rig. These ropes remove any excess slack in the material, especially if your fifth wheel is slightly shorter in length. Then toss the weighted straps underneath your fifth wheel to the other side and buckle them together. These straps keep the cover secure on your fifth wheel, preventing it from flapping in the wind and damaging the paint job.

Adco Olefin Zippered Access Doors

And if you still need to winterize or if you need to access one of the cargo compartments, you can use the zippered panels on the passenger's side to easily access the interior of your fifth wheel without having to completely remove the cover. You can also unzip the entire panel on the back of the fifth wheel so you can load and unload gear into your fifth wheel.

Beautiful cover but did not last thru one mildly windy storm. It ripped in 2 corners.We did put the pool noodles but the mild winds still ripped the cover.

The cover does have a three-year warranty. I can send you the warranty details if you are interested.


We chose this cover due to its construction and material; we needed a cover for protection against wet Pacific Northwest winters. We relied heavily on previous customer reviews to make our choice. Our order was filled quickly, despite weather delays in shipping. The cover was received in excellent condition, and was easy to unpackage. Highly recommend watching the installation video BEFORE installing, as it will greatly help. Or any installation video on
The cover took a couple hours for me to install by myself, and would likely install quicker with a helper. Additionally, our toy hauler has solar panels, and care should be taken to avoid the sharp corners on the panels. We ordered the 43 foot cover for our 41 foot trailer, and despite being oversized, the corners have cinch straps to tighten the cover. Plenty of straps to keep the cover from blowing around, and zippered access to the main entry door and rear ramp door. We are impressed with the construction and the fit, and got our rig covered in time for the next rainstorm. Time will tell about water resistance and durability, but so far, so good!


Easy to deploy cover but it is not as tough as it is advertised to be. Cheap plastic buckles could be more robust and after one season in Ohio cover started to come apart at a seam. I went thru the warranty process with picture sent and such and was told that a 6+ inch seam coming apart and opening up on the roof wasn’t warranted for complete replacement and they sent a cheap repair kit which totally no where near what their warranty states. be warned


Great looking and fits well. My 5th is 41' I ordered the 43'. I was able to install this solo, the trick was lay it out on the lawn roll it up inside out so all I had to do was lay it on the roof of the rv and unroll it then let the sides fall down each side of the trailer. The straps are a bit tricky to understand because there are some straps that just dont apply because of it being for all 5th wheels. The instructions dont discuss the straps well so it got 4 instead of 5 stars.


On my son’s 5th wheel, did not hear any complaints


Jake did an outstanding job serving my request and followed it up with ensuring the item shipped same day. I was shocked when it actually arrive the next day. I’ll be shopping here in the future.

I am sorry to hear that! These covers come with a three year warranty and I have sent that information over to you .


Wrong item was picked and sent to me. Called them and resending the correct cover and sending this one back. She was real helpful in fixing the issue.






I have a 2018 Lance 1995. This is the right size cover for this trailer. This is a good universal type cover ,but it is not a custom fit. This cover looks like it will work fine, but since the trailer has a curved from section it does not fit as well in the front as it does in the back. I have had to use bungee cords to help take up the slack and make a area for water to drain off the roof. I had to decide to either cover the propane tanks or the read bumper. I chose the tanks. If you get the next size up there will be too much cover and you will have issues dealing with the extra material. This cover is just long enough to reach the bottom of the siding with no extra material. It was arrived quickly from E Trailer. I suggest watching the installation video. It was helpful.


2 people installed the cover today in a light wind. I am a mechanical designer. I am not receiving any compensation for this review. This is our first cover going on our first RV. We ordered/received the the 22' long cover for the trailer which measures ~22' bumper to hitch ball plus some for the spare tire on the bumper. I am happy with the fit though it looks like it would fit a trailer whose "box" is about 3' longer and still go over the tanks and spare tire. I thought the ordering instructions said to include the tanks in the front and the bumper/spare tire in the back when determining the length.

There were no instructions except to "dull" sharp corners. The little foam tubes went on the gutter ends and I used black tape around sharp points on the bottom.

The only bad thing about the cover are the buckles/buckles: they worked but 1) they are too light duty, too weak, and the sections too thin in my opinion and 2) the design stinks because I want to hold the female end right where you press to release the buckle which was annoying but I figured out how to do it and it was more awkward than it needed to be considering other similar buckle types.

I got on the roof to pull the cover over from the side (not the front or back) over the ac, tv antenna, bathroom vent, etc and that worked well. It was too hard to pull the cover over the first top corner with me on a ladder and wife on the ground. If I could not get on the roof, we both would need to be on ladders. Or tie a rope to the straps and try to pull it over the top. Maybe try to pull it over from the front.

The fit is very good: good width, more than enough length and good height. I am glad the height was no taller so as to keep it from wrapping around the bottom which is sharp and the trim ends are sharp. We connected the underneath straps first, then the front and back then cinched the top and bottom corners to pull the whole thing tight along the perimeter.

All of the buckles are the same so I was able to repurpose some straps to wrap around the spare tire and bumper and connect to some other buckles for a better tie down arrangement. I would have liked a strap in the front middle to tie down under the tanks.

Otherwise, there are just the right number of straps underneath. I don't think more would help and less would make me nervous.

There are 2 flaps zipped on one side for a door at the front and/or the rear. I unzipped the front flap, sloppily rolled it up and attached the 3 velcro straps that hold the roll up. I had to undo 1 bottom strap from the flap so I need to rereview this after we have a good wind/rain storm but I think it will be ok. See pics. The trailer is parked in between a tree, shrubs, the house and the neighbors house so it is somewhat protected from some wind. Someone else may need to add a tie along the side bottom to take the place of the rolled up flap. When the flap is down, zipped, it is velcro'd at the bottom to the cover.

The perimeter cinch straps have a sleeve layered on top of the sleeve the strap is in which is great for 2 reasons. 1) you can stick your finger in it to grab it to push the cover back and pull out the strap, then 2) you can regrab it while pulling the strap through the buckle and keep the stress off the strap. This will keep the strap from scrapping and wearing while pulling through the buckle. I took pics and a video of this. And 3), this is another sleeve you can run a line through if needed.

Overall, I am very happy with this cover! It is reasonably thick material, aerated and the holes are covered with a flap to keep rain out, has a lot of straps which are well attached to the cover. The installation went better than expected at ~ 45 minutes and next time I expect to do it in half the time. The door access is a great feature. The cover went over the spare tire and the dual 20 lb tanks plus batteries in the front. One of the pics has the trailer model so you can see for yourself how well this cover fits this trailer. I expect this cover to last until a sharp corner some place tears a hole or the sun finally gets to it. The cover comes with a bag but I have not used it yet. And found a piece of velcro but not sure what for.

PS: Finally looked at the storage bag and found the instructions, self adhesive material to fix holes and weights that can be attached to the straps to throw underneath the vehicle (not over b/c the weight could break a window or make a dent) in a side pocket.


The quality and fit are very nice. For reference, my Outdoor RV measured 20'10" and additional 16" for the spare tire for total 22'2" Plenty of room to install. The roof fabric was ample for the AC unit. Also noted the cover is full grey material and the white top is added over the grey to make the roof double thick which is a nice bonus. Please note that the manufacturer's paperwork says this cover is NOT water proof.


I'll start out with the good. The cover fit excellent. The straps snugged up, the zipper access lined up perfectly and was generally easy to put on.
The bad is the cover has came apart in several spots, mostly corners and the satellite antenna area. None of these are sharp but for whatever reason it just rubbed right through. Cover was put on not quite a year ago and held up to the Minnesota winter seemingly fine but seasonal change wasn't kind too it.
I think the takeaway from this would be it would probably be good for 6 months or less but not beyond that.


This review is for fit and installation. The fit is good. Just a little short. Installation is easy. Took about an hour. I will review again in the spring as to the condition of the cover and camper.


Installed per video and first time worked out well. Video implied weighted straps for tossing under trailer and a storage bag were to be included, although neither were nor was that mentioned in description. Would have been nice, though if they had. It installed well and covered trailer as it should. Only time will tell how well it will hold up but I am pleased so far.


Just installed our new cover which replaces an older ADCO cover. Installation was easy and it fits great with a little room to spare. We have a 30 ft Cougat 26rls. Material quality seems to have improved.


After one year already is tearing quite a bit. I've only put it on/off about 6-7 times in the past year. Also interestingly, my solar panels are still able to get power even with cover on so undoubtedly it reduces the UV light quite a bit its not completely. Though I don't mind so much as it kinda trickle charges the batteries. This is being used on a 2022 Ember Overland 190MDB


Absolutely love this cover. I am 62, and was able to put this cover on myself (even being afraid of heights)! The gutter guards are a great addition and will prevent snags and or rips. Taking it off- I’ll ask for help, so the corners don’t get snagged on the lower ends. Great product thus far. I called and spoke w Ms Paula when I first ordered this cover, bc my camper is not as wide as most, but it is 20’. Had extra length, so I covered the propane cover and my hitch.


The cover had 2 rips after first use. the cover was on the 5th wheel for about four months and ripped at the downspouts of the trailer I did use the foam noodle inserts on the spouts that was supplied with the cover.


I sent my friends the link for the instructional video and in true guy fashion they said it was so easy they didn’t even hafta watch it. My 3 guy friends put it on in 25 minutes. “Good product, I’d totally have one if I owned an RV”, “Everything we needed (straps/padding) was included.” It fit great over my Starcraft Autumn Ridge 245DS. While I wasn’t involved in the process, they all assure me it went smoothly.


The tire covers are used every time I return the RV into storage, which is out in the Florida sun. The covers have held up masterfully and the tires have been very well protected. I can see the difference in the storage area where RVs do not use covers or they use a less durable brand. I am completely satisfied!


Nice cover. I ordered next size bigger and was able to fit over propane tank, battery holder and hitch, completely covered. Lots of straps for securing tight. Comes with extra patches in case of tears, gutter spout covers, ladder top cover, weighted straps, ok instructions, and storage bag. So far, no problems. Hopefully last several years as these covers are expensive.

  • Recommended Storage Cover for 2020 Forest River Sabre Fifth Wheel
    I recommend the Camco UltraGuard 5th Wheel Cover, # CAM45757. This is a UV-resistant, water-resistant cover that is made of polypropylene so it is great for wet climates.
