How to Measure 5th-Wheel Toy Hauler

Adco How to Measure 5th-Wheel Camper

To determine the proper fit, measure the length (front overhang to rear bumper including spare tire or ladder, where applicable) 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 fifth-wheel toy hauler 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 5th Wheel Cover

This contour-fit cover helps keep your fifth-wheel toy hauler 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 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 and rear offer access to your toy hauler during storage. Includes 4 Tyre Gards to protect your vehicle's wheels when stored.

Fabric Guards Against Elements

Adco Class C Tyvek Cover

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 toy hauler's surface. Additionally, the fabric beads water to eliminate pooling and ice build-up that can damage your toy hauler 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 fifth-wheel toy hauler 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

The cover features zippered panels on the passenger's side and rear so you can still access the interior of your toy hauler with the cover 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 toy hauler is in storage. The bag allows you to store the cover compactly in your vehicle or garage when not in use.

Very pleased with the cover. Easy to install, got more than I expected in tie downs, and wheel covers, even one for the spare wheel. Received the cover very quickly. Ordered a longer cover than I needed but had absolutely no problems. 590122

I got the cover in a short amount of time when ordered and it was easy to put on with little effort it fit well and looks great hope it holds up as well as it looks 720942

- 290-34858

When I bought, I assumed it would only be good for 2 years, and I think it will make that easily. Much less costly than covered storage. It's bulky, but as long as it's dry, one person can manage it without much problem as long as there's no breeze. Convenient zippered openings on passenger side are helpful, but it would be nice to have an opening on the driver side, too, to be able to turn on and off master power switch easier. I recommend discarding the sleeves provided for the gutters, and using tennis balls, instead. 500005

Have not put my ADCO Cover on as of yet but know others that have purchased the cover from etrailer with great success. I could not believe on how fast that Etrailer answered questions and the shipping was great. Will be using etrailer for other things I need for my camper 571805

- 290-34858

Etrailer have everything you need to keep you camper going....The complaint: The box that the cover was shipped in came very damaged. One edge was tapped with packing tape and all the other edges were beat up or ripped. The plastic bag covering the RV Cover appears undamaged. I will have to pull it out of the box to make sure but I am not going to open the cover until next fall. The cover looks ok from the box. I understand from other reviews over the years that I have read that this seems to be a regular complaint with larger items shipped from Etrailer. I guess just as long as the item itself is not damaged I am ok with it. 356872

- 290-34858

I attached picture of said cover after only being on the camper for a month and a half. My old cover lasted three seasons before needing replaced but this one is useless after a month. 640086

- 290-34858

I purchased this cover in order to keep my rv from the weather elements although it does good on rain and snow the wind however tore it up. If you can zoom in to the picture the only thing that was covered was the tires. We live in Amarillo texas so this product got put to the test with our wind and it failed. 730936

- 290-34858

So far so good. We have had an ADCO cover before and were pleased with our purchase. Three year warranty. I figure it will cost us about $125.00 per year to protect our camper. The sun and weather is tough on the cover. Rather the cover than my new camper. Will post some pictures after we install it. Love the price and service from etrailer. Easy to order, great service and they followed the shipment all the way to my door. Got an email to today telling me it was delivered. Got my mother-law to slide it in the house since I knew it was sitting on the front porch. Very, very pleased with the whole experience. Well done etrailer. 474303

Morning. It has not been on the camper 24/7 because we were using it. However it has been on for the last two months with about a month to go before we uncover it and begin to camp again. It has held up well even the days we had gale force winds. So I am very pleased. Thanks for the follow-up.

Awesome! Extremely quick response and very fast delivery didn't even take a week and package was on my door steps .... good job guys you have a customer for life ! Thx 880917

- 290-34858

Works great. Light and easy to install. Need patch material for small area’s that get puncher wounds like at downspout from drip rails. The covers that come with cover do not stay on very well on one side our other. Use small pet toy tennis balls slit with cross pattern and use long small bungee to connect across unit to hold in place. Drill small hole in tennis ball to hook bungee. Thanks 764300

- 290-34858

Just receive my cover today. Also just finished installing it. This is my second adco cover in 4 years for this fifth wheel. Usually have the cover on for 6 months while in Florida. It protects our camper very well. 750180

Shopped this on amazon, found 2 different prices but could never find why, checked here and got the explanation and got the same covers on etrailer for less, in 2 days and FREE shipping. I will check here before Amazon and will buy from etrailer again. 725503

- 290-34858

Great product from a great retailer, fits perfectly.Thanks etrailer!!! 598647

- 290-34858

I think because most trailers have the drip rail ends on 4 corners there should be some type of reenforcement on the corners to prevent tearing. Other than that seems like a good cover. Just put in for season so we’ll see how it holds up. 591695

- 290-34858

We just took it out of the box and was going to put it on and it already had a rip in it? Not impressed for $420 582168

havent taken it out of box yet but shipped fast and good price. 567641

BUYERS STAY AWAY from this product ... very Poor quality. I stopped by to check on the durability of cover on day 5 after covering my 5th wheel. I noticed All four top corners were torn, worst investment EVER !!! 509532

  • Storage Cover Recommendation for 2019 Highland Ridge Open Range 3X 387RBS
    The best cover option for your 2019 Highland Ridge Open Range 3X 387RBS is the Adco Tyvek # 290-34858 that you referenced. It does have toy hauler in the title but it fits non-toy hauler fifth wheels just fine as well. This cover is the correct size, offers the best protection for all climates, and also is easiest to install due to weighted straps that allow you to throw them under the RV instead of climbing under them.

  • Does the Adco Tyvek All-Climate + Wind RV Cover Fit Over 2 AC Units
    Yes it does! When Adco designed the Tyvek All-Climate + Wind RV Cover # 290-34858 they accounted for any rooftop accessories like your AC units. There is some extra material built-in to make sure that the entire cover fits like a glove plus they have integrated zippers so you can still gain access to the inside of your 5th wheel trailer with the cover installed.

    The Adco RV Cover w/Tyre Gards for 5th Wheel Trailer - All-Climate + Wind - Tyvek - 43-1/2' Long # 290-34858 is the longest storage cover we have and the best cover for all weather. The overall dimensions are 528" long x 106" wide x 132" tall. There is not a cover we carry that is the 53 feet you are seeking.

As long as the 42 feet that you measured includes the bumper, spare tire and ladder (but excludes the hitch) then this is the perfect fit for you.

  • Comparing the Camco UltraGuard 42 ft 5th Wheel Cover with the Camco Ultra-Shield
    The UltraGuard # CAM45759 is actually very similar to the Camco Ultra-Shield that you found. It doesn't have the Tyvek top panel, but the top panel is a triple layer SFS top panel that beads water on contact, providing maximum resistance to rainfall and snow. Basically it boils down to Tyvek being better for sunny climates where you need more UV protection and the SFS being better for wet climates. If your climate is much more sunny and you need the UV protection then we have the Adco cover...

  • Recommended 5th Wheel Trailer Cover to Protect Against Wind and Rain During Winter
    To protect your fifth wheel trailer from wind and rain I recommend the Adco Tyvek cover. However, finding the proper fit may be an issue depending on where you measured from. If you measured from the ground or considered any roof mounted items, like an AC unit, then # 290-34858 will be a good fit for you. It's 11 feet tall so if the 13-1/2 foot is just the trailer wall height then this won't work for you. If it will fit it's a great choice because it's designed specifically for extreme...

The 161" tall measurement that the manufacturer lists is measured from the ground to the top of the 5th wheel. The covers we offer for your trailer are not designed to go all the way to the ground so you need to measure the height of the box only. As long as this does not exceed 104" then the Camco UltraGuard 5th Wheel Cover part # CAM45759 will work for you. If it does exceed 104" then you will...
