There are thousands of aftermarket truck accessories available for every make and model of pickup truck. While a truck bed cover, also known as a tonneau cover, is arguably one of the best investments you can make, there are also a number of other great accessories that will help you get more from your truck and enhance your experience.

Tonneau Cover Style

The first thing to be aware of when selecting a tonneau cover for your truck and accessories to go with it is how the bed cover is mounted to the bed. There are a variety of covers that have mounting hardware that attaches the cover to the truck bed rail, but then the frame or cover itself completely covers the bed rail cap, immediately reducing the number of accessories that your truck bed cover will be compatible with. While the Peragon cover doesn’t work with every accessory, it does have some unique elements that allow for a wide variety of compatibility.

Please note that we cannot guarantee fitment of any aftermarket accessory with the Peragon cover. Compatibility often varies by truck model. The following post is provided as a resource to illustrate previously successful installations. With our 60-Day Free Trial, you have an industry-leading trial period to try out the Peragon cover and ensure that it is right for you. Please reach out to our support team for additional assistance.

Ladder Racks

Some of the most popular ladder racks available today are compatible with the Peragon retractable aluminum bed cover. The rails of the Peragon bed cover and corresponding brackets require uninterrupted contact with the top, inside edge of the bed side rails, the entire inside lip all around, and the entire top of the front bed rail, so keep this in mind when selecting a ladder rack. Ladder racks that mount to the inside edge via a clamp will not work with our cover. We recommend looking for racks that mount to the top side of your truck either by bolting or using the stake pockets.

Model Compatible Notes
Thule Trac Rac Slider Yes Purchase just the base rail and add accessories to it.
Adarac Yes Mounts to stake pocket holes
Apex HD Aluminum No Uses side bed lip clamp mounting system
Yakima Overhaul HD No Uses side bed lip clamp mounting system
TracRac Trac One No Uses side bed lip clamp mounting system
VanTech P3000 Partial Compatible natively on specific models like Honda Ridgeline (2017–current)
Adarac Aluminum Series Yes Mounts to stake pocket holes

Keep the following in mind as you consider ladder rack options and complete your installation:

  • Install the Peragon cover first to ensure it is aligned and operating correctly.
  • Peragon perimeter gaskets and side seals may need to be trimmed back away from the top edge stake pockets.
  • You may have to use a shimming spacer material in order to raise the rack footprint slightly to safely clear the top edge of the Peragon side rail. It is still essential that the Peragon tracks are completely level for smooth operation.

Bed Rails

Since bed rails generally mount to the stake hole pockets located on top of the bed rail sides, they typically do not interfere with installation and operation of the Peragon bed cover. You’ll find that bed covers that sit on the bed rail sides (non low-profile truck bed covers) cover up the stake hole pockets and will prevent you from using a variety of different tonneau covers. Bed rails are handy for a variety of things including securing cargo in the bed, as a handrail for accessing the cargo in your bed and enhancing the visual appeal of your truck.

Note: Some installations require minor trimming of the rubber seal or slipping the bed rail mounting base directly under the Peragon seal edge.

Model Compatible Notes
Putco Popup Yes Direct fitment without hardware interference
Putco Locker Yes Some perimeter seal trimming may be required near pockets
Putco Boss Conditional Varies across truck designs; minor adjustments or plate shaving can be expected

Bike Rack Mounted to Truck Bed Utility Rails

Bike & Cargo Racks

With such a massive variety of applications and needs, aftermarket products in this space are as seemingly infinite as bike components and tonneau covers. The long and short of it is that systems that rely on stake hole pockets or top-of-bed-rail (screw down) installation should be compatible. Hitch-mounted bike racks are oftentimes a great solution as well with our tonneau cover since the Peragon cover operates independently of the tailgate, allowing operation with hitch-mounted bicycles in place. There’s a wide array of truck bed rail mounted T-slots, tie-downs and tracks that you can deploy with different accessories to customize for your own needs.

Bed Extenders

A bed extender can be a convenient upgrade when you’re in need of extra room–just lower your tailgate and deploy your bed extender and your bed is fully functional with an extra 18-24″. Peragon is compatible with a couple different bed extenders and incompatible with others. Since the tonneau cover rails extend roughly 3″ into your bed on each side, careful selection of bed extenders is required. Below are some guidelines to aide you in selecting a compatible bed extender.


Fifth Wheel Trailer Connected to Truck Bed Hitch

Fifth Wheel

Peragon retractable tonneau covers are popular among fifth wheel travel trailer owners because of its unique open-into-the-bed design that preserves rear visibility while driving and allows you to keep the cover in place. The cover works with many different fifth wheel hitches and the following will help you determine if your fifth wheel setup will be compatible. Due to the significant variation of hitch designs and truck models, we don’t publish recommendations, but you can always contact our Sales & Support team for additional information.

Hitch Clearance

The top of the fifth wheel hitch must be at least one inch below the top of your truck bed rail. The most forward part of your hitch must be at least 20 inches or more from the inside wall at the cab.

Top of hitch must be 1″ or more below top of truck bed rail. Forward part of hitch must be 20″ or more from cab-end bed wall.

King Pin Box and Rail Clearance

Peragon rails extend into the bed roughly 3 inches on each side. Depending on your setup this can affect your turn radius. King pin box may come into contact with rails if making a hard turn. Peragon rails protrude about 1 inch above your truck bed rail. You will want to check to make sure you have adequate room between the top of the Peragon rail and bottom of fifth wheel cap. It is recommended to have a minimum of 5 inches of clearance.

Headache Racks

Headache racks are one of the most popular truck bed accessories out there, and for good reason–they protect your rear window from debris and cargo that you’re hauling, but can also offer storage and other features like accessory lighting. The Peragon cover works with rail mounted headache racks that don’t mount on the inside lip of the bed rail. In some cases, an additional adapter can raise your headache rack and allow for tonneau cover clearance and expanded compatibility.

Model Compatible Notes
GMC Sierra OEM Rack Yes Direct drop-in configuration
Aries Headache Rack Yes Clearance verified across full open/retract patterns
Magnum Headache Rack Yes Locks flush behind cab structure
Back Rack Yes Requires specific hardware block tonneau cover adaptor kit

Dual Liner Modular Protective Bed Bed Liner System

Bed Liners

Likely the most common aftermarket upgrade of a pickup truck, bed liners are nearly ubiquitous. There are many different styles, most of which are compatible with the Peragon cover. Spray-in liners are fully compatible, even sprayed over-the-rail. The BedRug is fully compatible. Under-the-rail plastic drop-in liners will work fine, with some requiring minor modification. If the plastic liner wraps over the front of the bed or over the tailgate, that’s fine too. Over-the-rail plastic liners that wrap over the sides of the truck bed may not be compatible or may require extensive modification.

Pendaliner Yes Under the rail variant setup works natively
Husky Liners / Bed Mats Yes Under the rail configuration works natively

Dodge Ram Side Cargo Utility T-Track Rail System

Cargo Management Systems

Cargo management systems (also known as utility track systems) are becoming more popular in truck beds straight from the factory, though most are still installed as aftermarket accessories. These systems allow you to plug in a variety of different accessories for different functionality from cargo cleats to bed organizers and trays. In some cases, these systems interfere with the Peragon tonneau cover so we’ve provided the below guide to aide you in understanding compatibility.
