Adco Olefin Installed

Summer is over, and you're worried about your travel trailer getting dirty and damaged in storage during high winds, snow flurries, and spring thunderstorms. Whether you're storing your trailer in the sunny south, rainy northwest, or snowy north, this heavy-duty cover is designed to protect your trailer in any climate. When you keep your trailer 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 trailer 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 trailer. 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 trailer.



How to Measure Your Travel Trailer


Adco How to Measure Travel Trailer

To determine if this cover will work for you, measure the overall length of your trailer from the very front of the trailer 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 tongue of your trailer, so don't include those in your measurements. Then measure the overall height from the bottom of the chassis to the top of your trailer. 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 Travel Trailer


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 trailer, so install those first. Then unroll the cover and carefully spread it evenly around your trailer, 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 trailer is slightly shorter in length. Then toss the weighted straps underneath your trailer to the other side and buckle them together. These straps keep the cover secure on your trailer, preventing it from flapping in the wind and damaging the paint job.


Adco Olefin Zippered Access Door

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 trailer without having to completely remove the cover.

I was worried everything wouldn't be in the box considering the shape it was in when it arrived, but I give credit for that to UPS. My wife, daughter and I got the cover put on our 2016 Keystone Laredo 333BH in right at about 45 minutes after we came up with a plan of attack. Should have had everybody watch the movie. Things went smoothly but I forgot the pool noodles, so we have to go back and correct some possible oversights. The passenger's side and back pictures were not good enough to post.



by:

My only complaint is that the size of the cover fits 34 - 37 ft. My unit is 34 and I had to play with the front in order to get a tight fit.

The cover is still working great. I was able to put it on for the winter in a fraction of the time it took the first time. I rolled it up in the Spring where I could easily place it on the top of the camper and just roll it out nicely the secure it down. My wife helped and we completed it in about 15-20 minutes easy.

Extremely happy with this cover. We had used an ADCO cover for our 30 foot trailer before, and it lasted 6 years. It got some small tears in it over those years, but using the extra patch sheets and some duct tape it kept the tears from growing. This new cover was an upgrade from the one we had before. The old one had the two year warranty and the new one has the three year. It also has the cinch straps and buckles on the upper corners and lower corners of th cover. They really help give a good fit to the trailer. It also seems the top material is a little more durable than our old one had. We live in the Pacific Northwest where the climate is relatively mild. However it has held up well with any winds we have had. Really glad we got another ADCO cover. Hoping and expect we will get another 6 or more years out of this one.



by:

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.



by:

Considering the cost of the cover, I expected it to last more than a few months. I contacted etrailer and Adco several times but neither of them would address the premature cover failure. My advice is to invest in a good wax or coating to protect if from the sun, not this cover. The cover was installed on a Momentum 397TH while it was parked in Arizona. I carried the cover up the ladder this first time to install it, but it is heavy so the second time I installed it, I put it in the back of the truck and used a rope to pull it up the front of the camper and onto the roof. Installation goes much better if you have one person on the roof and another on the ground. The cover was strapped at tightly as possible and adjusted frequently to keep the cover tight, but it flaps in the wind so much that it caused scuff marks on the nose and sides of the camper. The roof flapped in the wind so much that it broke a roof vent cover. Tears in the cover developed on the front, rear side, and roof. I won't be using this cover again.



by:

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.



by:

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.



by:

Cover fits great and survived our Wisconsin winter in good shape - and protected our asset (camper) ! We created a small tear pulling the cover over a rain gutter (too small for the noodle protector) - so watch for sharp covers.



by:

The cover is very nice. It should be marked more obviously as to the inside vs. the outside. The straps after they are tightened hang down and could provide 'ladders' for mice, I used the rubber bands to roll them up and keep them off the ground



by:

Took the extra time to install pool noodles around solar panels and ladder, took about an hour to install. I usually lay the cover out on the ground and re roll it to make it easier once on the roof. Being in florida I've only ever gotten about 2 years out of these covers before the fabric starts to disintegrate from the sun. This is my third cover now.



by:

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.



by:

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.



by:

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.



by:

In only 9 months the stitching is coming apart and the material is so cheap that it basically turns to powder wherever it recieves the most sun. Also dont be fooled by the “3 year Warranty” claim. They only warranty once so if you make a claim in the early year after purchase and it happens again you are left out of warranty. Worst part of all is they charge you for the shipping.



by:

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.



by:

Even after padding the corners before installing the cover, it had multiple holes within weeks. ETrailer was contacted and only offered patch kits not return. Would not purchase



by:

Fits nice and secure with straps to prevent wind damage. Labeled front/back along with roof different color makes for easier placement of cover. Zipper to access door. Rain gutter extender covers to prevent cover damage. Breathable material to prevent mold or mildew. Appears to be very durable
Very happy with my purchase!



by:

Thank you for such a pleasant ordering experience, from the moment I placed the order to the very quick arrival of our cover. The cover, with my son's help, went on very nicely. All of the straps to secure the cover are great. I am sure the cover will protect our RV for a very long time.

  • Options For Cover For 2019 Forest River Salem 33TS Travel Trailer
    Hello Charles, From what I can find your 2019 Forest River Salem 33TS measures 38' 9" (465") which includes the trailer tongue. That's important because the longest covers for a travel trailer measure 37' 3" (447"), but aren't designed to go over the tongue. So I highly recommend measuring the length of your Salem from the front (not including the tongue) to the rear bumper to ensure the length of its body. Trailer tongues are usually about 3' long, so the right cover is one that is going...
