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.

Good cover but had to duct tape a few areas after material tore in the ladder area. 899040

Great cover fit well good quality 898109

- 290-34847

Cover was a little big, our trailer is 34 ft. long but it did fit fairly well. It could have held up better in my opinion as when we took it off in the spring there was a rather large tear in the roof section and several small tears at some of the corners. I have patched these and will hopefully be able to get one more year out of it. Will probably try a different manufacturer next time. 883496

Hi, I bought this for a birthday gift and it won't be opened until Friday. I would like to say that your service was fast and efficient! I really appreciate that. From the outside everything looks in good order. Thank you for being a good supplier. I think the birthday boy will be very happy. John 730846

It could be taller, but our trailer is very tall. We love the cover. Very well made, and the zippers make it easy to get inside when we need to. 724935

I’ve love this cover I have a 37 foot toy Hauler covers fits perfect, came with a handy storage bag for the cover. Keeps the sun from fading you camper 705922

To help prevent premature wear and tear on the cover, it is best to measure your camper from the front of the body, excluding the tongue and trailer jack. The cover is shaped to fit the body of a travel trailer and cinch around the corners, keeping the cover in place even in the wind.
-- Victoria B - 10/02/2019

Pretty good I have a few small tears in the front of the cover and one in the side near the back overall it’s not a bad cover

Thank you for your review. We do carry the Adco Universal RV Cover Patch Kit part # 290-2093
Adco Universal RV Cover Patch Kit - 6 Colors
to patch up any small tears so they do not become larger.

- 290-34847

It seems to do its job, covered well and nice straps on the bottom with venting to allow for the wind. Although you have to pad even moderate corners very well with much more than what they provide as it tears very easily. I used swim noodles. But any little exposed corners or radius tore through. 692318

- 290-34847

Cover lasted about 8 months. Started tearing along the roof section. Finally gave way. ADCO sent me a new one under warranty ([small] shipping fee). I installed that one this weekend. Photos show the old one splitting down the top and ending up on both sides of the trailer and the newly installed cover. 670650

- 290-34847

After a year, still holding up great, still looks good, a little hard to put on by yourself, but other than that, I would definitely recommend this product to anyone who wants to protect their investment 635866

Great product and best price. 594700

Just installed the cover on our camper this past weekend. Seems of good quality. Fits well. Was able to snug it up well. Used towels under the cover at the eve spouts and other sharp corners. We'll see how the cover looks come spring. 583945

We have a 2018 Keystone Laredo 335MK (38 Ft. total length) and the ADCO RV works great. Since the trailer sits outside at our storage location I feel better covering it to help protect for the elements, I have checked the trailer after it rained for 3 days and the RV was dry under the cover. ADCO makes a super product and etrailer is always great to work with. I highly recommend this cover for anyone who wants to take care of your RV and help keep it looking like new. 568336

- 290-34847

Very quick shipping. I got what I ordered and am eager to try it out. It looks like it is much better than the Lego style blocks offered elsewhere. I like the fact that I don't have to guess how many blocks I will need, run it up on the blocks I have put together and hope I don't fall off the back side and have to try again. That happened with the Lego style. I will try to update my review after I have tried it out. 447277

- 290-34847

As always excellent service from etrailer my first source for all my trailer needs, 2 cargo trailers, single and tandem axle, Travel trailer tandem axle, boat trailer tandem axle 432294

generally still satisfied, this will be its second winter. Only concern is the light duty material on fronts and sides. some rodent damage to front, material is very thin and posed no problem for mice? Ive duct taped the damage and will make sure and store in a closed container next Spring, makes me wonder though if I wont be replacing it again in a few years. I note comments from Travis 112017 re tire covers made of thin material, this is the same issue I have with the front side of the cover.

Review from a similar All-Climate Plus Wind in RV Covers

After one year of heavy snow, wind, rain, summer heat and sunshine, cover has no tears, is waterproof and is really as good as new. Excellent buy, great price. Would recommend to anyone wanting a well made cover. Wheel covers, which are included, are a real bonus. 713842

Gives good coverage and protection. Suffered a few accidental tears. Works well for the money.

Review from a similar All-Climate Plus Wind in RV Covers

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

Very nice cover, only problem you must pad or cover the gutter down spouts or they will rip the cover. From the wind blowing.

Review from a similar All-Climate Plus Wind in RV Covers

Shipping was super fast. Thanks everyone who had apart in helping me out with questions (Bryan). The box is big and I hope to install the cover as soon as the snow melts here in Minnesota. I've bought a few of this brand of cover before. They hold up for a few years if you keep them on tight and snugged down from the wind. Padded at the sharp corners. Thanks Dino 611241

The cover is working great. I dont expect it to last forever. The sun can destroy anything. Good price for the cover. Use extraa pull ties and bungees

  • Travel Trailer Cover Recommendation for 2020 Grand Design Reflection 315RLTS
    The Adco Tyvek part # 290-34847 is a fit for your 2020 Grand Design Reflection 315RLTS and would be the best option to go with. It's height is 102 inches but this is the height from the top to the bottom of the body of the camper not including the height that AC units adds. The Tyvek provides the best protection in all climates and has the easiest install too since it has weighted straps that you'd throw underneath the camper instead of having to crawl under it.

  • Cover Recommendation for Park Model Trailer that is 35 Feet Long
    Your Park Model Trailer is basically a camper trailer with a slide out which we have several covers that will work well. Since your trailer is 35 feet long the # 290-34847 would work great as it is designed for 34-37 foot long trailers. The slide out of your trailer would need to be slid in though.

  • Best Storage Cover for 2019 Forest River Cherokee 294BH For Wet Climate
    For your 2019 Forest River Cherokee 294BH the best cover for a wet climate is the Adco Tyvek All-Climate Cover part # 290-34847 as this is the correct size and the best for protection against rain. It's not completely waterproof as that would mean that it could hold moisture in which would allow mold and mildew to build up but it does bead water off of it which repels nearly all of it and is also breathable to allow any moisture to dry up.

  • 2016 Premier Ultra Lite Bullet 29RKPR Storage Cover Recommendation
    When the RV covers are rated by length they take into account the standard accessories that they'll have like roof top AC units, spare tires, awnings etc. So the best way to pick out a cover based on length is like the picture I attached and from the back of the trailer body to the front behind the propane tanks basically. I looked up your 2016 Premier Ultra Lite Bullet 29RKPR and the length listed is 34-1/2 feet so your 35 foot figure is correct. The Adco cover part # 290-34847...
