TRUKD T Series Double Decker Bed Rack Configuration
TRUKD T Series Double Decker Bed Rack Configuration
The Double Decker Bed Rack is built for those who need more room to haul, and refuse to compromise. This setup combines our 24.5" uprights with an additional set of crossbars and brackets to create two levels of mounting space. The upper tier is perfect for rooftop tents and awnings, while the lower level gives you added storage for hard cases, water containers, fuel cans, or camp essentials like tables and chairs. Whether you're gearing up for work or a long-haul adventure, this rack turns your truck into a fully modular gear hauler.
Load Rating:

Overview
Two-level truck bed rack built around 24.5" T Series uprights — upper deck for an RTT and awning, lower deck for hard cases, fuel cells, and camp gear. 10-gauge 304 stainless uprights and aerospace aluminum crossbars, textured black powder coat, made in Pittsburgh, PA. Fits 13 truck models across three mount options.
Key features
- Two independent decks — 24.5" uprights (18" base + 6" risers) create an upper tier for RTTs and awnings, and a lower tier for storage. Both run on T-slot aluminum extrusion channels.
- 304 stainless uprights — 10-gauge, e-coated, never rust. Aerospace aluminum crossbars won't corrode or fatigue from road vibration.
- 300 lb driving / 1,000 lb parked — 150 lb per bar dynamic, 500 lb per bar static. Designed for loaded RTT setups at highway speed.
- Three mount options — Utility Rails (stake pockets), T-Slot Tonneau Cover (retractable covers only), or Bed Clamps — depending on your truck and existing bed setup.
- 13 truck fitments — Toyota Tacoma and Tundra, Jeep Gladiator, Nissan Frontier and Titan, Ford F-150/250/350, Maverick, and Ranger, Chevy Colorado/GMC Canyon, Silverado/GMC Sierra, and RAM Classic/Tapered Bed.
- Lifetime guarantee — TRUKD backs the T Series against product integrity defects.
- Made in Pittsburgh, PA — Designed, welded, and assembled in the USA.
Use cases
Double Decker owners are running RTT + awning on the upper tier with a full lower deck of Pelican cases and fuel for remote trips. The T-Slot variant lets you keep a retractable tonneau cover fully functional beneath the rack — bed security for the daily, roof platform for the weekend. The T-slot extrusion channels on every bar accept MOLLE hardware, Rotopax mounts, antenna brackets, and more without drilling.

Which tonneau covers work with the T-Slot mount?
Retractable covers only — Retrax and Roll'n'Lock are the confirmed compatible brands. The T-Slot mount slides into the cover's existing channel, so the tonneau stays fully functional under the rack. Maximum tonneau width: 69.75".
Tri-fold and hard-folding covers (BakFlip, Extang, UnderCover Flex, etc.) are not compatible with T-Slot. If you have one of those, select Utility Rails (stake-pocket mount) or Bed Clamps instead.
What's the difference between Utility Rails, T-Slot, and Bed Clamps?
Utility Rails use your truck's factory bed rail stake pockets — clean install, no drilling, and the rack sits above any existing bed liner. Available on: Toyota Tacoma, Toyota Tundra, Jeep Gladiator, Nissan Frontier, Nissan Titan.
T-Slot Tonneau Cover mounts into the T-slot channels of a retractable tonneau, keeping it operational beneath the rack. Available on all 13 fitments.
Bed Clamps clamp directly to the top of the bed walls — good if you don't have stake pockets and don't run a retractable tonneau. Available on most fitments except Toyota Tacoma.
How's highway stability with a rooftop tent — any bounce or flex?
The T Series uprights are 10-gauge welded stainless; the system doesn't flex the way thinner tube racks can. Rated 300 lb/set driving, 150 lb per bar, so a typical 100–150 lb RTT is well within spec on one bar. Dynamic flex is more commonly a function of the RTT's profile (a tall, soft-sided tent acts like a sail) than the rack itself. Don't exceed 150 lb per bar at speed and you're in spec.
How hard is the install? Can I do it myself?
Plan for about 3.5 hours. You'll need SAE hand tools only — Hex Drivers 5/32 and 7/32, a 9/16" and 1/2" socket wrench, and a tape measure. No power tools and no metric tools — the install guide is explicit on both. No drilling into the truck.
Step 7 (lifting the assembled rack onto the bed as a single unit) is doable solo but TRUKD recommends a second set of hands to avoid damage to the rack or personal injury. Plan for that. If you're running T-Slot, you'll also likely need to pull the tonneau cover off to mount the brackets, then reinstall it.
What's included in the box?
4 upright brackets, 4 riser brackets (the 6" extensions that bring total height to 24.5"), 4 faceplates, 2 crossbars, 2 front-to-back extrusions, 4 front-to-back connector brackets, bar end caps, and all hardware bags (3/8-16 bolts, 1/4-20 screws, shoulder washers, carriage bolts, lock nuts). Mount-specific hardware — Utility Rail T-nuts, Bed Clamps, or T-Slot plates — is included per your variant selection. RTT and awning sold separately. Premium bar end caps are sold separately.
What's the warranty?
TRUKD backs the T Series with a lifetime guarantee against product integrity defects.
How does the Double Decker compare to the standard T Series configurations?
The standard T Series comes in 6.5"–18.5" upright heights — single-level platforms. The Double Decker uses 24.5" uprights (18" base + 6" riser) and adds a dedicated second deck with its own crossbars and mounting brackets. If you're running one RTT and don't need substantial lower-tier storage, the 12.5" or 18.5" T Series is lighter and sits lower. If you want two fully independent loading levels — RTT up top, full gear rack below — the Double Decker is the configuration.
