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. 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 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.

I really like this cover. Everything has held together so far and it fits the trailer nicely!




by:

The Adco Olefin HD All-Climate trailer cover has excellent quality and workmanship. It was very easy to install and adjust to my travel trailer. Based on its quality, I expect it to hold up well during this winter in Northern Illinois.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


Looks like a nice cover, but we bought it for a 20’ Carson Racer trailer and it’s more than a foot too short! The trailer measures exactly 20’ and it’s way too short! Bummer!!


Comments
You mentioned that it was too short. I wanted to make sure that are measuring the length of the front bumper to rear bumper including spare tire or ladder, where applicable and the sidewall height from the undercarriage to the top of the natural roof line.
-- Etrailer Expert Jenny N - 08/09/2022
Our trailer is an unmodified Carson Racer 20’ rectangle box. It measures exactly 20’ long. Cover was way too short! Ended up ordering the 20-22’ cover and it fits perfectly with a small amount of extra room. You can see in the picture that if we put the back end where it needed to be, it would not fit over the front at all! We tried positioning the top white part before letting the sides down. Nothing worked. Definitely not the right size by the manufacturer.
-- comment by: Chris - 08/09/2022
I am sorry that it was not a fit. With the camper being exactly 20 feet I recommend using the next size up cover which would be part # AD47ZR

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


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.

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.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


We bought this cover for a cargo trailer. This is the second one we have used. The first one lasted nearly 4 years, being in the weather the entire time, before we had to replace it. My cargo trailer looks new because of the protection of the cover. This cover did not include tire covers so you would need to order separately.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


Very well manufactured rv cover. It perfectly fits my 28 foot travel trailer. It is approximately 5 feet too long but it works for me because I have a utility rack on the back of trailer. The side zippers are good but I wished they were more heavy duty. But they open and close easily. Overall I am very satisfied. I would recommend this cover.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


I have used Adco covers for years to keep my 2007 camper looking and operating like new. I tried a more expensive marine cover but it was more difficult to put on and didn't last any longer than the non-woven Adco covers so I switched back.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


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.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


I just put the cover on and it appears to be well made, only time will tell.
My only issue was the length of the "belly" straps, which go under the trailer to secure it. My trailer is 18ft and it has a AC and 2 roof vents on the roof. I ordered the cover for a 18-20 ft trailer, but some of the "belly" straps weren't long enough to go under the trailer and snap on the other side.


Comments
These covers usually account for vents and AC on top of the roof and provide extra room for those items. I would measure the width of your RV to see if the 100 inches wide are enough for you.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


Due to supply chain issues etrailer was the only outlet with the cover I wanted. I have not installed this cover yet but was very pleased with a similar cover from ADCO. Normally avoid etrailer due to a refused return because their part lookup was not accurate and I had packed the bearings.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


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.

Pretty easy to install by yourself if there’s no wind. The 22’ to 24’ cover fit perfectly on our 26’ TT (23’ box). Corners pull in nicely and end straps work well. Plenty of under-trailer straps. Zippers for entry to the TT door are nice. It’s not been on long so we’ll see how it does this winter.

Review from a similar Olefin HD All-Climate RV Cover in RV Covers


Recent purchase. I like the straps to secure the cover. However, the straps should be significantly wider with longer/deeper anchor points. Minimum of 2 inches wide and 3" wide straps wouldn't be too much. First time we put the cover on one of the anchor points failed. We live in a high wind area and although I do appreciate the straps provided we have to add two circumference straps just to keep the cover on.

Chances are even if the undercarriage straps were wider and more securely anchored we would still need to use circumference straps to keep the cover on.

Don't interpret these comments as being dissatisfied. We like the camper cover and the undercarriage straps are very welcome. Just disappointed that we've already had a strap failure after the first use.

I'd would have included photos to show both the strap tear and the circumference straps we use but didn't know that would be an option for this review. If I can get back to this review I will include them in the near future.
