How to Measure Your Travel Trailer

How to Measure Your Class C RV

To determine the proper fit, measure the length (not including the trailer tongue) and sidewall height (undercarriage to the top of the natural roof line). This cover is designed to accommodate rooftop accessories such as AC units and vents.


Choose Cover by Climate

Adco Climate Map

The climate where you are storing your travel trailer will help determine which cover to choose. This Tyvek All-Climate + Wind cover is designed for use in all climates located on the map above.


Adco Travel Trailer Cover

This contour-fit cover helps keep your travel trailer dry and well protected when not in use. It features a 3-layer DuPont Tyvek top and 3-layer polypropylene sides to protect against sun, rain, mold, and mildew in a all climates. Elastic corners and a rope cinching system allows you to draw the cover in tight over your vehicle. Zippered panels on passenger's side offer access to your trailer during storage. Includes 4 Tyre Gards to protect your vehicle's wheels when stored.


Fabric Guards Against Elements

Adco Tyvek

The top panel is constructed of triple-layer DuPont Tyvek fabric that is stronger and more UV resistant when compared to standard polypropylene covers. It blocks 99.8 of damaging UV rays while keeping the interior cool through infrared heat reflection. It also prevents 98 percent of dirt and dust particles from reaching the trailer's surface. Additionally, the fabric beads water to eliminate pooling and ice build-up that can damage your trailer or cover. And the material resists acid rain, bird droppings, tree sap, dirt, dust, and other forms of environmental pollution that cause black streaks.


The sides of the cover are made of a non-abrasive, triple-layer polypropylene. This high-performance, non-woven fabric is water resistant and breathable to prevent the growth of mold and mildew.


Air Vents Help Cover Breathe

Adco Class C Air Vents

Air vents on the sides allow air to escape the cover in moderate winds to prevent billowing. These built-in vents also help the cover breathe to prevent mold and mildew.


Straps and Elastic Corners Ensure Snug Fit

Adco Corner and Cinching System

The cover is designed to fit snugly over your travel trailer for a clean look and better protection from the elements. Elasticized corners grip your vehicle tightly, and they are reinforced to reduce wear and prevent tears and snags. Cinch ropes in front and back remove slack and reduce billowing.


Adco Strap and Buckles

Weighted straps with buckles run beneath your vehicle to secure the cover in place. The weighted ends allow you to easily toss the straps from one side of the vehicle to the other. Once buckled, the straps can be pulled tight to ensure the cover is securely fastened so it won't blow away with the wind.


Zippered Panels Offer Access

Adco Tyvek

The cover features zippered panels on the passenger's side to allow access to the interior of your vehicle while the cover is installed.


Storage and Protection

Adco Class C accessories

A ladder cap, rain gutter spout protectors, 4 Tyre Gards, and a storage bag are included with the cover. Place the cap on top of your vehicle's ladder and the protectors over your rain gutter spouts to reduce wear on the cover. The Tyre Gards protect your wheels while trailer is in storage. The bag allows you to store the cover compactly in your vehicle or garage when not in use.

Most of it held together, but there were significant tears in parts of the cover. The winds in our area are quite strong at times and it showed. If you don’t live in an area where wind gusts of 60mph occur at times then it will hold up well! 697347

Owned the cover for over 1 year now. Great cover and easy to install. We live in Canada and this cover helped protect our trailer from the harsh elements of snow, wind & ice. When we removed the cover in the spring our RV was as clean as when we covered it. Only issue is we have a small tear in the top corner where the drip channel extends out from the trailer. The trailer comes with covers for the drip channel to help protect the cover but they do not stay in place. Overall a great product. Ordering the cover through E-Trailer was easy and shipping was fast. I have ordered other products from E-Trailer and have had an excellent experience each time. 578422

Just got my ADCO cover (thanks for the fast delivery) and covered my travel trailer for the season. I store the trailer in an area with ruthless sun (altitude: 7200 feet) and wind. I think all covers in this environment perform disappointingly, judging by the experience of others at my storage facility. ADCO's tyvek cover seems to do the best for the money, usually giving me two solid seasons (three, if I am willing to do a little repair work). And covering the trailer according to the instructions can be done as a one-man job without too much difficulty. Makes the whole winterization issue much less intimidating. I don't actually use the included tire (tyre?) guards, as I prefer vinyl covers that I believe will block the sun and reflect heat away from the tires better. Thanks, ADCO and etrailer! 562873

After one year, the cover is hanging in there. Due to my work schedule, it had to keep my travel trailer covered all winter it survived a bomb cyclone that hit the area and most of the summer. It has one small tear that will be easy to fix, then it will go back on for the winter, as soon as I am finished with the trailer for the season.

I like it! It looks good on for sure. Although. if you have ANY rough spots on your RV it will rub a hole in the cover. I’ve only put it on and have yet to remove it so hopefully there will be no surprises. Tip: before you cover your rig be sure and treat or protect any rough spots on your RV. I use cut to size plastic tubing with a slice down the side to cover any questionable area... it grips naturally and is easy to put on and remove. 670695

Very pleased with this cover and the help I received on the correct size for my travel trailer. My order was shipped the same day and arrived within 2 days. I have purchased from e-trailer in the past and have always been pleased with there prices and quick shipping. I will continue to use e-trailer as my primary source in the future. 714063

Cover came in mail promptly. Great product, fits perfect. High quality materials and easy to install. Strap system on the cover assures me this will last through anything shy of a hurricane. Has been in use for approx 1month and has been taken off and put back on with ease 3 times since recieving it. Tire covers work great too! I would recommend this cover! 679539

I am really happy with the quality of the product and the ease of installation. The only recommendation I have is I would think it would come from the factory rolled up ready to install. Otherwise, no complaints and I am happy with the cover. There is plenty of tie-downs and grommets etc. 669802

It fir our Coachmen Apex Nano perfectly. I found the quality and value to be very good. I thought that the instructions could be better. As a 50 + year old that does use technology, It would have been nice to have written instructions i could follow in the driveway vs the 1 page vague instructions and had to keep referring to cell phone vid. Overall I love the product and i'm happy I bought it 579518

So far so good. It was very easy to put on our trailer. Winter has just begun so we'll see in spring. I love how it has the zipper sides so if we need to get into the trailer at any time we can. 588680

On year two with this cover and its holding up well. It did tare in a couple spots but I think that was my fault - it was really windy and I was trying to do it myself. I finally had to get the wife help me and we got it done with out any problems.

I have only had it installed for a week. Bought it so my red travel trailer won't turn pink. Installation was easy (I watched a video first). It made it thru a heavy wind day. Did not use tire covers as I had some already. I think a good expectation would be 3 seasons of use. 592931

After one season two of the straps have already rotted and broke, the zippers for the door are not tall enough to get the door open, the cover seems a little too long for the trailer 865507

They don't hold up in the Arizona sun. The cover starts breaking down in only a few months and by one year needs replacing. This is the second Adco All-Climate Plus Wind RV Cover I have purchased for this trailer. The previous one fell apart in the same manner. 804937

After a year of use, I find the cover does exactly as I had hoped. It keeps the camper clean and even cool during the summer. We had someone try to break into our camper and tear a portion of the fabric. Even though I am marginally proficient with a sewing machine, the fabric was easy to work with and even allowed me to reinforce some area. I recommend the cover if your camper has to stay outside when not in use. 796940

Overall good product and very quick delivery. etrailer price was $150 less than my local dealer quoted even with my new customer "discount". Instructions for strap placement could be better but it can be figured out with a little effort after you get the cover on the rig. Opening for door on a Lance 1685 needs a top zipper or velcro strap as well as the vertical zipper and bottom velcro strap so that three sides are opened. the present setup does not allow the door to open without stressing the cover at the top of the door. The cover is not adequately reinforced where it meets the rain gutter extensions and will rapidly wear through in any kind of wind unless you add padding (which I did) before covering 749430

Speedy delivery, even with the Christmas rush. Installed quickly on our Cherokee Wolf Pup 16FQ travel trailer. We’ll see how well it does with our Ohio winters . 734426



- 290-34840
by:

the fit is good enough , but why would anyone do all the work to make such a cover and not use a better fabric ? tybec is too light and the wind blows holes anywhere there's a edge, so after having the cover on for 6 months it was alresdy full of holes, which I'm able to fix , but if there was a better fabric available , it would then match the craftmanship 734187

I really like the cover, it's light and protects well. 730252

Goes on well, great fit, but tears too easily. After a few days, punctures from rain spouts. Then, a few weeks later we had a windstorm, and it tore completely in half right down the middle of of the top cover. Great product if you are in a wund-free area. 729103



- 290-34840

Put the cover on for the start of the second year and found one small wear spot other then that it looks like new after one winter of Oklahoma's winds. I have a Sonic venture and it has a rounded front. The fit on the front is baggy and flaps in the wind. If the fit was better on the front of the trailer I would have given it 5 stars. In all fairness it is a generic cover and not a custom fit. 728471



- 290-34840
by:

The initial installation in 2018 was a bit more work than expected because my trailer roof should not be walked on, but a long rope to pull the cover across the top and some excellent assistance from my bride of 53 years enabled it to be accomplished in relatively short order. I did cut pieces of foam insulation to plastic tie over the sharper corners of the trailer, and over the roof antenna bracket so I wouldn't lose to cover to wind damage. The cover withstood a long, snowy, and cold Montana winter in excellent condition. Pulled the cover out of the extra large tote I store it a few days ago to cover the trailer again for the coming winter. I am very pleased with the cover, its appearance when installed,and its durability. I highly recommend this cover -- and recommend following the installation instructions! Also recommend etrailer and crew for their assistance in obtaining this cover for my particular camp trailer. 726631

    Based on my research it does look like your Winnebago 2106 DS Micro Minnie features an overall length of 21 feet and 11 inches like you mentioned, however this length is including the tongue.

This will be ideal for you as Adco site says do not just go by the measurements from the manufacturer they instruct to measure from the furthest point forward on your trailer but not the tongue. For your trailer we know it's 15 foot 5 inch so the # 290-52239 is correct.
