## Bed liners & bed mats

A mat or liner stops cargo sliding around under the cover and protects the paint. Over-the-rail liners can clash with clamp-on covers, so check before you buy.

- Bed liner**BedRug Classic bed liner (BRQ15SCK), charcoal grey**Works with any coverA full-coverage foam-backed carpet-style liner for the floor, walls and tailgate: kneeling-friendly, and it stops cargo sliding around under a cover. Listing fitment: 2015–2024 Ford F-150 5'7" (5.5 ft) bed. Per the listing, the BRZSPRAYON install kit is required over a spray-in liner. If you run a clamp-on cover, make sure nothing sits on top of the bed rail where the clamps grip.[Check price](https://www.amazon.com/dp/B00R6LZUW4?tag=truckcoverguide.com-20)
- Bed liner**Herculiner HCL1B8 roll-on bed liner kit, black, 1 gal**Works with any coverThe cheap DIY route to a textured, sealed bed floor. A coated bed sits under any cover type without changing how clamps or rails fit. One-gallon kit; check the coverage on the listing against your bed size before you buy.[Check price](https://www.amazon.com/dp/B0002TDUW4?tag=truckcoverguide.com-20)
- Bed mat**Husky Liners custom-fit rubberized bed mat (16008)**Works with any coverA rubberized mat with air-dry nibs underneath, so water that gets past a soft cover's seals can drain instead of sitting on the paint. Listing fitment: 2015–2026 Ford F-150 and 2022–2026 F-150 Lightning, 5'7" bed. Per the listing, it will not fit over a drop-in bed liner.[Check price](https://www.amazon.com/dp/B084J67MZR?tag=truckcoverguide.com-20)
- Bed mat**Rough Country heavy-duty rubber bed mat (RCM671)**Works with any coverA cheaper rubber mat that protects the floor and keeps cargo from sliding into the tailgate. Listing fitment: 2015–2027 Ford F-150, Lightning and Raptor, 5'7" (67 in) bed.[Check price](https://www.amazon.com/dp/B0985NPF7M?tag=truckcoverguide.com-20)

## Cargo management

Bars, straps, nets and slide-out trays keep a covered bed organized, because you can't see what's rolling around under a closed cover.

- Cargo management**DECKED drawer system (XR7)**Works with any coverTwo bed-length lockable drawers under a flat deck rated for 2,000 lb of cargo per the listing. Under a locking cover, it turns the bed into secure tool storage. Listing fitment: 2019–current Ram 1500 (DT) 6'4" bed, not RamBox. A drawer system raises the bed floor, which cuts the height left under a cover. DECKED sells a separate model for each truck and bed length.[Check price](https://www.amazon.com/dp/B0CLMHPNR2?tag=truckcoverguide.com-20)
- Cargo management**Keeper ratcheting cargo bar, 40–70 in (05059)**Works with any coverPins groceries and gear against the bulkhead or tailgate so nothing slides around under a closed cover. It sits below rail height, so the cover closes over it. 40–70 in span; measure between your bed walls at the height you'll use it.[Check price](https://www.amazon.com/dp/B0000AZ9KS?tag=truckcoverguide.com-20)
- Cargo management**Migaven heavy-duty truck bed cargo net, 4 × 6 ft**Works with any coverThe fallback when a load sticks up past the rails and the cover has to stay open: a stretch net over the bed keeps loose items in.[Check price](https://www.amazon.com/dp/B0C5CZBXYW?tag=truckcoverguide.com-20)
- Cargo management**Rhino USA ratchet straps, 1 in × 15 ft (4-pack)**Works with any coverTie-downs for loads strapped to a bed rack, or tall cargo you haul with a roll-up or folding cover open.[Check price](https://www.amazon.com/dp/B01N7P7EOX?tag=truckcoverguide.com-20)
- Cargo management**Rough Country slide-out truck bed cargo tray (10209)**Works with any coverBrings small items to the tailgate so you don't have to crawl under a cover to reach the front of the bed. Rough Country says the 4 in tray fits under any bed cover. Listing fitment: Trucks with a 5'7" or longer bed (tray is 62.3 × 23.6 × 4 in). Per the listing, fits beds 5'7" or longer; 5 ft midsize beds are too short.[Check price](https://www.amazon.com/dp/B0DQVKJ4L7?tag=truckcoverguide.com-20)

## Tailgate locks & assists
[Guide →](https://truckcoverguide.com/posts/most-secure-tonneau-covers/)
Most covers are only as secure as your tailgate lock. If your truck doesn't lock its tailgate, fix that first.

- Tailgate**Dee Zee DZ43204 tailgate assist**Works with any coverA gas-strut damper so the tailgate lowers slowly instead of dropping. Handy when you're reaching into a covered bed with your hands full. Listing fitment: 2015–current Ford F-150.[Check price](https://www.amazon.com/dp/B01AP2BNS0?tag=truckcoverguide.com-20)
- Tailgate**Dee Zee DZ43301 tailgate assist**Works with any coverThe same slow-drop damper for older-body Ram trucks. Listing fitment: 2009–2018 Ram 1500, 2019+ Ram 1500 Classic, 2010+ Ram 2500/3500. Per the listing title, this does not cover the 2019+ new-body Ram 1500 (DT).[Check price](https://www.amazon.com/dp/B00GUF74HQ?tag=truckcoverguide.com-20)
- Tailgate**Pop & Lock Gate Defender universal tailgate lock (PL9900)**Works with any coverA locking tailgate is half of a secure bed: most hard covers lock by latching under a closed tailgate, so a tailgate that opens defeats the cover. This lock also stops tailgate theft. Sold as a universal fit for most trucks; many newer trucks already have a factory tailgate lock.[Check price](https://www.amazon.com/dp/B00TPXG0NO?tag=truckcoverguide.com-20)

## Floor liners

Not for the bed, but bought in the same trip: custom-fit cab floor liners for the trucks we cover most.

- Floor liners**Husky Liners X-act Contour floor liners, front & 2nd row (53468)**Works with any coverA slightly cheaper three-piece cab liner set with raised edges that hold spills. Listing fitment: 2021–2027 Ford F-150 and 2022–2025 Lightning SuperCrew with fold-flat storage. For SuperCrew cabs with fold-flat underseat storage only, per the listing.[Check price](https://www.amazon.com/dp/B094QV23J9?tag=truckcoverguide.com-20)
- Floor liners**WeatherTech FloorLiners, 1st & 2nd row, black (44697-1-6)**Works with any coverLaser-measured, US-made cab liners with channels that hold mud and snowmelt. Listing fitment: 2021–2026 Ford F-150 / Raptor and 2022–2023 Lightning SuperCrew. Per the listing: 1st-row bucket seats with the fold-flat rear storage box. Other seat and storage layouts use different part numbers.[Check price](https://www.amazon.com/dp/B0999SP5VC?tag=truckcoverguide.com-20)

## Cover care
[Guide →](https://truckcoverguide.com/posts/are-tonneau-covers-waterproof/)

Check your cover maker's care instructions first; some makers specify their own cleaners.[Check price](https://www.amazon.com/dp/B00JG3OIFU?tag=truckcoverguide.com-20)

Compatibility checked November 12, 2026. Confirm your truck and cover on the listing before buying.

## What to buy first
If your truck's tailgate doesn't lock, a tailgate lock comes before anything else: every soft cover and most hard folders are secured only by the tailgate. Next, a bed mat stops cargo sliding into the bulkhead under a closed cover, and on vinyl covers, a UV protectant applied a few times a year keeps the material supple. Our [security guide](https://truckcoverguide.com/posts/most-secure-tonneau-covers/) explains which covers have their own key.

## Bed racks and covers
A bed rack lets you carry kayaks, ladders, lumber or a rooftop tent above the bed while the cover stays closed. Two designs work: racks that clamp to the outside of the bed rails, leaving room for the cover's rails inside, and racks that bolt into T-slot rails built into some covers (BAK's Revolver X4ts and MX4 TS, Retrax T-slot versions and Roll-N-Lock's M-Series XT). Compatibility is specific to each cover and truck, so check both makers' fit guides. Our [covers with a bed rack](https://truckcoverguide.com/posts/tonneau-cover-with-bed-rack/) guide goes through the options.

## Bed liners with a cover
Under-the-rail drop-in liners, spray-in liners, rubber mats and carpet-style liners all work with clamp-on covers. Over-the-rail liners are the problem: the cover's clamps need to grip the bed rail, and several makers (Tyger, for example) say you'll need to cut small notches for the clamps. Retractable covers route drain tubes through the bed's drain holes, which may mean opening a hole in a spray-in liner.

## Caring for a cover
Wash a cover with mild soap or a dedicated cleaner rather than harsh degreasers, keep the seals free of grit, and check that drain tubes are clear before winter. Vinyl and rubber benefit from a UV protectant.
