Overall I love the product and the idea, but I’m not happy with quality and finish. Needs more work to be the product it describes to be.

The pros:
Ton of space. I can put so much in bed of my truck now. Especially having a fifth wheel hitch in bed of truck, I still have the space to put other things. Great for shopping or leaving stuff in bed and not feel like it will go missing. Still have not camped with it but I look forward to.
Able to take apart alone without help like with other bed campers. Takes about 30 min but it can legit be done by one person.
Lots of light inside during day. I’m glad I got one with window but at times I wish it was without for more privacy. I’m split on that.
If you have a dog it’s great. Also, when you remove windows inside and back you just have roof to protect from sun with tons of air. Super cool.

The cons:
NOT water proof. If you have things inside that can’t get wet… in rain they will. Leaks everywhere. Not horrible but everything you don't want to get wet will be wet. Still need a water tight tote for clothes and electronics.
The walls can not support highway speed. So I had to add broom sticks across frame on indie to give windows support otherwise I feel like they will get sucked in and ripped off.
Not sealed. Dirt and dust gets in through the corners of camper. As well that vacuum issue. So the corners of windows and and frame have big gaps where LOTS of dirt gets in. Do not follow anyone on dirt road. Everything inside will have a coat of dirt.

If the canvas has no holes on stitching and seals are better it will be a great product. Also, if you have a bedliner (like rihnoliner like I do) forget getting velcro to stick to front for securing to truck. I had to buy a 1”X1” aluminium angle iron and rivet it to bed of truck. Then to that smooth surface I used the velcro tape. That’s only way. I can add picture of that when I get a minute.
I thought after it got wet a few times and was on truck for a few months the holes on roof would close up, but they did not. Holes where stitching is leaks water.
Overall I still love it, and would buy it again, but quality and build is just not there. I take mine apart once a month to pull my fifth wheel and having the ability to do that alone without help is still worth it for me.


It’s a nice looking topper. But I had difficulty putting it together. The top poles with holes punched in them for quick release extensions had large burrs. I had to file out each hole. Also the back window took three people pulling on it to get it stretched enough to get to the passenger side zipper. I’m hoping that after time and some hot weather it will stretch and form better and be more user friendly.


good material!!

The windows, need
to be 1" or 1/2" bigger, so when you start driving the wind won't open them from the top of each window; from time to time you have to adjust the upper channels were you clip the windows cause the wind open them little by little.

If you change the idea of the upper channels for a third zipper will make it stronger against the wind.


I purchased the canvas "topper" for my 2014 Toyota Tacoma. I wanted something that was lighter than a conventional fiberglass topper. I also wanted something that i could move or remove easily to haul taller objects in the back (Motorcycles).

Installation was recommended for 1.5 hours. I took my time and did it alone, it was almost exactly 1.5 hours. If possible I recommend 2 people to install. The canvas is tight when new and some stretching was in order.

Once installed i spent the next day driving through rain for a total of 312 miles. No issues with leakage or no extra wind noise.

Overall I would give it a 10 out of 10. It exceeded my expectations.

Lastly e trailer made the transaction very smooth and delivered it super fast and in great shape. They continue to make me a lifetime customer.


1970 Toyota Land Cruiser Good top, quick shipping and a fair price. Easy to install and looks good. The only drawback is the area above the doors where they meet the top leaks in the rain. (Using Bestop half-door uppers on Aqualu lower half-doors) Hate it looks so much like a Jeep but there aren't a lot to choose from.


Most is awesome. I love the windows. The one downfall is the bed rail rails are not strong at all they do bend I had to bolt the rails to the bed with 5 bolts on each side because they just kept bending up.


Where do I start. Let’s see. Manufacturer says place the rails 63 1/2 inches apart. My truck bed is 65 inches wide. So the rail hangs over the inside of the bed, half on the bed rails.
Every time fold down the top the center bar comes apart, no snap on the bar or on the canvas like the video shows.
J channels are worthless, they should have used snaps or full length zippers on the windows, I can’t see the j channels lasting any length of time. Slid the J channels together like the video shows. Let go and the window falls out. I spent over a hour trying to put in one window like they said, I gave up
Would I buy this again?. Absolutely not. It’s great concept but has some design flaws.
I have received a lot of compliments on the truck and top.
Little do they know it’s pretty much just for show. When it fails I will go fiberglass


Very good quality. Getting the side windows installed was a challenge they wouldn’t snap down and stay, wound up sliding them in length wise which was difficult had to spray w-D 40 in the track.


Overall the product is working. It was a lot of instructions and took longer than the recommended 1 hour and half. I would recommend a two person team as well. Putting the tarp on, locking it in place and zipping it was no easy process. The written instruction was not clear and the labeling of the parts could have been simple (i.e driver side, passenger side etc.) Also I watched the video several times,the folding and open does not work that smoothly. Maybe because I have a 8 foot bed and not a 6 foot truck bed. Overall the product works and it's serving it purpose.


Directions were terribly inaccurate, spacer needs to go in the rear clamp, set screws are a terrible fit due to burs and powder coat over the threads, rear bar had the seal installed backwards allowing water in. Spent most of the two hours deburring the holes drilled for the connectors. Material is very high quality but components are lacking. Not happy at all, should have been an hour install, I have the best top Jeep top and am very happy with it but this install was a mess. Needs improvement.


Prompt service, good product with straight forward instruction.
I bought this Toyota FJ40 with no top dint want to spin to much on a hard top but still needed a top, so I opted for a soft top, did my homework on the internet and came across ETRAILER.
I'm glad I found them, got the best deal and fast delivery. The good fit just made my truck look much better.


We live in Portland, OR, where it rains a lot for about 8 months of the year. The first few months, our Topper was great! Then Summer came and we decided to put the top down (collapse it). When the rain season began again, we put the top back up. To our surprise it was leaking horribly through the seams and through the fabric. We contacted etrailer and they said we should contact Bestop directly. Bestop said that etrailer sold us the wrong model for our truck and they would not honor the warranty. We went back to etrailer and they were happy to replace our Topper for us with one condition - we pay for return shipping. Well, it turns out, return shipping would cost us over $400! That is more than half of what we paid for our Topper. We gave up and decided it was not worth it. I DO NOT recommend this Topper or Bestop in general. eTrailer was responsive, but unfortunately their return policy makes it unfeasible to return a bulky item like this. Very frustrated with the product and warranty policy. DO NOT BUY.


The quality of the bestop that was on my Jeep is why I chose to get one for my truck instead of the other brand. Etrailer was great to deal with. They matched a lower price that I had found online, and got the top shipped out immediately even late on a Friday afternoon. It showed up on Wednesday, earlier than predicted. Now for the top... I expected a great fit and easy installation. The rails and bows were simple, But the bed on my Dodge is wider at the front than the rear. The top is made for the narrower width, so the rails barely sit on top of the bedrails, exposing the stake pockets on the bed, and making the whole thing look goofy. Highly disappointing! The way side panels attach is another bad design. I expected a zipper across the top, like the jeep tops, but the plastic j channel set up was a real pain to keep in place. Im thinking maybe I should've ordered the Softtopper.


Look great but very difficult to open/retract. Installer had a very hard time. It's a very tight fit, and one of the side panel zippers broke because of this. Is it possible to get a warranty repair on the zipper?


The biggest piece of garbage! Even worse than their jeep tops. I will definitely be sending this product back and will never buy bestop brand again.


Great top my only issue is the front Velcro comes off and the front panel flops in the wind I have to stop crawl into bed and reattach the Velcro this happens about 1 a month


The box was in pieces ... but no parts were missing.

2019 RAM 3500 LONG BED


The instructions were wonderful and it made the installation very easy. The cover has proved itself on several of my camping trips, keeping my gear dry and clean. I should have ordered it sooner.


Did the job as expected. Provided the flexible covering we needed on the cross country move. Latching system on the windows an rear flap could be improved..


The cover is nice. The back window closes very very poorly. It does not fit well and is not held in place at all....

The top is nice. Keeps out rain and snow nicely.

Removing the top for folding it away is awful. If you simply remove the four rail clamps, then it's very easy and quick... Whatever you do, don't unfold it in the cold or try to bend the plastic windows in the cold.... They crack...


Thanks' for your help. It's a good start. I will call as I need more.


Easy to find and order and shipping came without any issues


The box looks like the product was examined due to the fact that all sides of the box are were opened. Then sealed with clear tape.


Great option to a hard topper. Have had no issues. It has performed well.


This is a really nice looking, quality top. I had someone else install it, so I can't personally speak about that aspect, but it didn't sound like it was too difficult. I like that there are a lot of different options for opening the windows; you can use it in all sorts of configurations. The only problem so far is that I have to lift up on the passenger door a little to close it and get it to latch. Not sure if this has to do with the top or the Jeep, since the Jeep was just restored and it wouldn't surprise me if something on the Jeep is a little out of alignment. If you are looking for a top for your Jeep I don't think you could do any better than this one.

  • How To Measure Your Truck Bed For A Cover
    To measure your truck's bed for a cover you'll just need to measure the internal dimensions of the box, meaning from the bulkhead to the tailgate. I see that you're looking at the Bestop Supertop, which only comes in either a 5-3/4' bed size # B77318-35 or a 6-1/2' bed size # B77319-35.
