Which truck has the widest bed?

Of the four here, the Ram 1500 — 51.0 inches between the wheelhouses and about 66 inches of exterior rail width. The Silverado has the widest floor at about 71.4 in and the deepest bed at 22.4 in.

Are F-150, Silverado and Ram tool boxes interchangeable?

For crossover boxes, largely yes — 64, 65 and 66 inches of rail width all take the same full-size 69 and 72 inch classes. Covers, liners and racks are a different matter entirely and are model, year and body-style specific.

Why will a full-size bed slide not fit a Tacoma?

Because a standard slide is 48 inches wide and the Tacoma has 44.7 inches between the wheel wells. Mid-size slide and drawer ranges exist as separate products; the full-size ones physically do not go in.

Which bed is deepest?

The Silverado 1500, at 22.4 inches of box height. The F-150 is 21.4 in, the Ram 1500 21.4-21.5 in and the Tacoma 20.2 in on a Double Cab or 21.2 in on an XtraCab. Two inches across a bed is real volume.

Do these dimensions change by cab configuration?

Not for the half-tons — the cargo box figures hold across cabs for a given bed length. The Tacoma is the exception: its bed depth differs between Double Cab (20.2 in) and XtraCab (21.2 in).

How we know:Spec-verifiedOwner-report-verifiedWhat these mean

The two numbers that decide almost every bed accessory purchase are the exterior bed rail width and the interior width between the wheel wells. Here they are for the four trucks this site covers, alongside the lengths and depths.

Published bed dimensions. Exterior rail widths from UWS's bed width guide; interior figures from each manufacturer's published specifications. Blank cells are figures the manufacturer does not publish or configurations that do not exist.
	F-150	Silverado 1500	Ram 1500	Tacoma
Exterior bed rail width	about 65 in	about 64 in	about 66 in	about 57 in
Width between wheel wells	50.6 in	50.63 in	51.0 in	44.7 in
Maximum interior width	Not published	about 71.4 in	66.4 in	about 53 in

How to read it

Exterior bed rail width is the crossover tool box number. It is measured outside-to-outside across the top of the rails nearest the cab, and a box's advertised length is larger because the ends overhang.
Width between wheel wells is the floor number. It decides chests, drawer modules and bed slides. A standard 48-inch slide needs this to be comfortably above 48, which rules out the Tacoma.
Bed depth decides whether a load clears the rails, and how much vertical capacity a drawer system's raised floor costs you.
Length at floor is what you order drawer systems and slides against, and it is exact rather than approximate.

The three things this table tells you at a glance

The three half-tons are interchangeable for tool box purposes. 64, 65 and 66 inches of rail width all take the same full-size boxes. The differences between these trucks matter for covers and liners, not for boxes.
The Tacoma is a different market. Seven to nine inches narrower at the rails and six inches narrower at the wheel wells. Full-size parts do not transfer.
The Silverado has the deepest bed. 22.4 inches against 20.2 on a Double Cab Tacoma. Two inches of depth across a bed is real volume, and it is the reason a drawer system costs proportionally less capacity on a Silverado.

What this table cannot tell you

Three things decide fitment that no dimension captures, and all three cause more wrong orders than the numbers do:

Body-style splits. The 2019 Silverado and the 2019-onward Ram were each sold as a new body style and a Classic in the same year, taking different covers, liners and racks.
Factory bed options. RamBox changes the Ram's usable bed entirely. Ford's Pro tailgate, factory bed steps and fold-flat rear floor storage all exclude specific parts.
Electric variants. The electric F-150 has different bed hardware — charge outlets, tie-down positions, drain locations — so mats and liners need to state compatibility.

UWS EC10473 69-inch Heavy-Wall Aluminum Crossover

Best for: The box you buy once

Our score8.6/10

$759.95at Amazon

Price as of October 5, 2026. #ad

Heavy-wall aluminum, a foam-filled RigidCore lid that does not flex when you sit on it, and a low profile that still clears most rear glass. This is the crossover to buy if you intend to keep the truck.

Who should skip it. Skip it on a 5'5" short bed. At 69 inches it will sit on the rails, but you lose a disproportionate share of a short bed and the money is better spent on a side-mount pair.

Build: 9.4
Weather seal: 8.8
Security: 8.6
Bed usability: 8.0
Value: 7.4

What works

Foam-filled lid does not oil-can under body weight
Low profile clears rear glass on most full-size crew cabs
Heavy-wall extrusion survives being used as a step
Gas struts are serviceable rather than sealed units

What does not

Among the most expensive aluminum crossovers on the shelf
69 in is a full-size length — not a mid-size answer
Matte black shows scuffs more than diamond plate

Published specifications

Length: 69 in
Profile: Low profile
Material: Heavy-wall aluminum
Lid: RigidCore foam-filled, single lid
Finish: Matte black
Published capacity: Not published

EASYBERG 60-inch Aluminum Crossover for Mid-Size Pickups

Best for: A crossover that actually fits a mid-size bed

Our score7.4/10

$229.99at Amazon

Price as of October 5, 2026. #ad

60 inches, which is the size class that matters: a mid-size truck's exterior rail width is around 57 in, and the 69 and 72 in boxes everyone else sells are built for the mid sixties. This one is not.

Who should skip it. Budget aluminum with a budget latch. It solves the fitment problem, not the security problem.

Build: 6.8
Weather seal: 6.8
Security: 6.2
Bed usability: 8.6
Value: 9.0

What works

60 in clears mid-size rails
Light enough to fit single-handed
Cheapest correct-length option

What does not

Thin-wall aluminum
Latch is the weak point
Silver finish shows every scuff

Published specifications

Length: 60 in
Material: Aluminum
Fitment: Mid-size pickups
Finish: Silver

Keeper Adjustable Ratcheting Cargo Bar, 40-70 in

Best for: Stopping the load sliding to the bulkhead

Our score8.4/10

$37.99at Amazon

$50.99 25% off · Price as of October 5, 2026. #ad

A 40-70 in ratcheting bar that braces across the bed and holds a load against the tailgate. It is the cheapest piece of kit on this site and it stops more rattling, sliding and scratched paint than anything else you can buy for the money.

Who should skip it. It is a brace, not a wall. It does not partition the bed into compartments and it will not hold a heavy load on its own.

Build: 7.8
Capacity: 6.8
Install: 9.8
Day-to-day access: 9.4
Value: 9.6

What works

Costs less than a tank of fuel
Ratchet tension holds without tools
Stores flat behind the seat when not in use

What does not

Keeps a load in place; does not compartmentalize the bed
Rubber pads mark a painted bed over time
Load rating not published

Published specifications

Adjustment range: 40-70 in
Type: Ratcheting cargo bar
Finish: Black / silver
Published load rating: Not published

Figures from the Manufacturer listing.

Fits

Any bed 40 to 70 in wide between the walls
Mid-size and full-size trucks
