Product Description
2019-2027 RAM 2500 & 3500 owners want one setup that does it all, and the Fas-Top® combo delivers exactly that: a soft, low-profile tonneau cover for daily hauling that rises into a full soft topper whenever you need camper-shell height and weather protection — all on the same rails.
This combo is built for the 2019-2027 RAM 2500 & 3500 (available for the 6'4" / 8' beds). Pick your bed length and rail finish; it clamps on with no drilling, the canvas rolls up over the cab for full bed access, and it reconfigures between low tonneau and full topper in minutes.
Every Fas-Top® is built on a heavy-duty aluminum rail frame with extreme-duty latches and marine-grade, double-stitched canvas — one of the toughest soft-cover systems on the market, and made in the USA. It clamps to your bed rails with no drilling, and the canvas rolls up over the cab for full bed access in seconds. As an authorized DÜHA-backed dealer, you get a purpose-built, American-made cover with real support behind it — not a generic, one-size-fits-all cover.
For the Ram HD owner who tows and hauls and needs weathertight, flexible bed storage, the Fas-Top® combo means never choosing between a low tonneau and a full topper — it's both, on demand.

I am extremely happy with is product. It was simple to assemble and install. I love that I was able to do it all alone. I did contact customer service before it was ever delivered and they responded quickly and answered my question promptly also.
I love this topper! It fits my needs perfectly: regular tonneau cover most of the time and easy to set up camper shell when more space is needed. The quality is top notch, love the imperial hardware too! Highly recommend!
I purchased the Fas-Top early last fall before the hunting season kicked in. I couldn't be happier with its modularity, durability, and convenient storage. I assembled and installed the topper in less than 2 hours, without any professional help. The topper kept my gear dry and protected, while maintaining its structure throughout all kinds of terrain and inclement weather. When I was in between trips, I could easily drop the top and lean on the tonneau cover, with the topper stored in the front of the bed or simply hanging on the wall of my garage. I would recommend the Fas-Top to anyone who doesn't want a permanent solution and is seeking some versatility. I'd buy it again in a heartbeat.
Great company and great product. Arrived in good shape very quickly. Tonneau cover looks great and was very easy to set up. Topper looks great. Set up was a little more difficult. But probably more me than the product. I did find good videos that helped.
Overall. Great products. Love that the topper is easy to setup and tear down. Can’t wait to use it more.
Bought a new truck and wanted a bed cover but also needed more space for going on vacations. The soft topper + Tonneau cover was a perfect match for me. The Tonneau cover gives my bed coverage with a sporty look and when I need more storage space I just flip up the soft topper and all my gear is protected from the elements.

Easy to instal and Fit great
Topper combo is exactly as presented. Very sturdy and easy to switch around.
Installation is straightforward with instructions presented a couple of different ways. Assembly does require a modest amount of innate mechanical ability but the results are completely worth it. Great job DUHA!
Looking forward to years of usefulness.
A very sweet set up. After put the topper on I ran it through a touchless car wash. The topper kept 99% of the water out of the bed of my pickup truck. The water on the car wash is set at 175 psi. just so everyone knows what the DUHA top can handle. thank you for a amazing topper.
This is a tough product to review. Build quality is very high, and the materials seem quite durable. Fits on my truck well also.
My major gripe is with the instructions. They are incredibly lacking. This repeatedly caused me to build sections, get two or three steps further, and have to take apart everything I had done so far. Even watching the installation video as a supplement, many many critical pieces of information are missed.
Here are some examples:
- The topper/tonneau is attached to the truck using a rail that is pre-installed on the truck. Instructions show a bolt being inserted into this rail. No mention of the square custom washer that needs to be used.
- 5 square nuts are pre-installed in the rail. Instructions have you install the tonneau before the topper. It is critical that you use the correct 3 nuts to install the tonneau or else the topper can't be installed. No mention of which nuts to use.
- When assembling the topper, instructions say to match the colors. Yellow to yellow, white to white, etc. More than half of the connections had no color indicator leaving you to guess (I guessed wrong).
- Instructions in multiple cases say "install this onto the truck" with a cropped picture that gives no context if we're looking at the passenger or driver side of the truck. No indicator in the picture to understand what is left/right/front/back.
- Instructions have you "attach the topper's velcro to the tonneau's velcro". The topper has velcro on both sides at this joint and the instructions make no mention of which side to attach. This is critical and will pull off in later steps if you choose the wrong side.
- Instructions have you assemble the whole topper and raise it on the truck. No mention of starting the zippers. When the topper is assembled and you try to start the zippers they are super deep into a nook that is being stretched because it's assembled that it's almost impossible to start the zippers.
I really enjoy the product so far. The instructions are unbelievable.
Thank you for your purchase and for your feedback on the installation. We hope you are enjoying the Tonneau/Topper combo as much as many others do.
