Ram 2500 and 3500 Flatbed for Truck Campers
The Ram 2500 and 3500 are 3/4 ton and 1 ton trucks, which is exactly what an Aluma Tray is built for. Your box length picks the model. Short box takes the 6.75', an 8 foot long box takes the 8', and a 1 ton chassis cab at 60 inch cab to axle takes the HD-60.
Fitment
Which Aluma Tray fits your Ram 2500 or 3500
Find your configuration. The box length picks the flatbed, not the trim or the engine.

Starting prices are MSRP for the flatbed. Nothing on this page is a build total. Required items are priced separately below because they depend on your truck.
Not sure which box you have? Measure the box floor from the bulkhead to the inside of the tailgate and send us the number. We confirm the flatbed in writing before you order.
The cab and the drivetrain don't change the flatbed either. Regular cab, extended cab or crew cab, 4x4 or 2WD: the box length decides.
Ram 2500 short bed flatbed
The flatbed for a Ram 2500 short bed is the Aluma Tray 6.75' short bed flatbed. It fits the Ram 2500 and the single rear wheel Ram 3500 with the short box. It is rated to 3,000 lbs evenly distributed, starts at $11,819 USD, and carries four locking under-deck boxes below a Rhino Lined deck.
A Ram 2500 aluminum flatbed on the long box is the Aluma Tray 8', rated to 3,000 lbs evenly distributed and from $12,879 USD. So a flatbed for a Ram 2500 long bed and a short bed are two different trays, and the box floor length is how you tell which one you need.
The 6.75' does not take the dually fender kit. If you run a short box Ram 3500 on dual rear wheels, talk to us before you order.
A Ram Mega Cab flatbed is the same answer. The Mega Cab has a short box, so a Mega Cab 2500 or 3500 takes the Aluma Tray 6.75'. On a Mega Cab dually, talk to us first, because the dually fender kit is not offered on the 6.75'.
Ram 3500 dually flatbed
A Ram 3500 dually flatbed needs the dually fender kit, $2,268 USD. The kit is available on the 8', HD-60, and HD-60-HC, and not on the 6.75'.
On a dual rear wheel Ram 3500 with the 8 foot long box, the flatbed is the 8' Ram dually flatbed plus the kit. A dually Ram 3500 chassis cab at 60 inch cab to axle takes the Aluma Tray HD-60 plus the kit.
A single rear wheel Ram 3500 (SRW) needs no fenders. The Ram 3500 flatbed then follows the box: 6.75' for the short box, 8' for the long box, HD-60 for the chassis cab.
Every dual rear wheel option in one place: the dually flatbed page.
Ram truck bed replacement
An Aluma Tray is a full Ram truck bed replacement. The factory box comes off and an aluminum flatbed for the Ram 3500 or 2500 goes on in its place, isolated from the chassis with powder coated steel mounts and urethane bushings. That is the Ram 3500 flatbed conversion, and the Ram 2500 flatbed conversion works the same way: the tray replaces the box rather than sitting in it.
A Ram 3500 flatbed price starts at $11,819 USD for the 6.75', $12,879 USD for the 8' and $17,820 USD for the HD-60. The tray to chassis mounting kit ($1,166) and the fuel kit are priced on their own, and your dealer quotes the installation.
The fuel and DEF fills move into the bulkhead for filling from the deck, and the lights and a 4 and 7 pin connector come on the tray.
If your Ram has rear parking sensors in the factory bumper, the rear sensor bar ($398) mounts under the rear apron and reuses them. It fits Ram trucks.
Trim doesn't change the tray. A Ram 3500 Laramie takes the same flatbed as a Tradesman. Plenty of people still search for a Dodge Ram 3500 flatbed. The fitment on this page is for the Ram 2500 and 3500, so send us your model year and we confirm the fit in writing.
Ram 3500 chassis cab flatbed
A flatbed for a Ram 3500 cab and chassis at 60 inch cab to axle is the Aluma Tray HD-60 chassis cab flatbed, rated to 5,000 lbs evenly distributed and from $17,820 USD with the bulkhead included. Not sure of your measurement? Here is how to measure cab to axle.
The HD-60 is not limited to the 1 ton. It fits any domestic commercial chassis cab with a 60 inch cab to axle, so a Ram 4500 or 5500 built at 60 inch takes it too.
For an OEV High Country camper on the same chassis, the Aluma Tray HD-60-HC is the tray built for it.
Between the 6.75', the 8' and the HD-60, that covers Ram 3500 flatbed trucks from short box to chassis cab. Compare every model on aluminum flatbed prices.

Before you order
What every build needs
The starting price is the flatbed on its own. These items are priced by your truck, so they sit as their own line items.
- Tray to chassis mounting kitSpecific kit determined by your truck$1,166
- Fuel kit$290 gas, $290 diesel without DEF, $542 diesel with DEFPriced by truck
- Dually fendersOnly if your truck is dual rear wheel$2,268
If your truck is dual rear wheel
The dually fender extension kit is required on a dual rear wheel truck. It is available on the 8', HD-60 and HD-60-HC. It is not offered on the 6.75', so talk to us first if you run a dually short box.
Bulkheads
The 6.75' and 8' need a front bulkhead, priced separately. The HD-60 includes its 7 inch bulkhead in the starting price. See all options and pricing.
Heavier chassis cabs
The HD-60 fits any domestic commercial chassis cab with a 60 inch cab to axle, not only the 1 ton. If your Ram 4500 or 5500 is built at 60 inch cab to axle, the HD-60 fits it. Here is how to measure cab to axle.
For an 84 inch cab to axle chassis, see the HD-84.

Next question
Will your camper work on it?
Your truck picks the flatbed. Your camper is a separate question, and it depends on the camper's footprint and weight rather than the brand. Most hard side slide-in and flatbed campers run on an Aluma Tray.
Send us your Ram 2500 or 3500, your camper model and its dimensions and we will confirm the pairing in writing.

Questions
Ram 2500 and 3500 flatbed questions
Which Aluma Tray fits a Ram 2500?
The Aluma Tray 6.75' fits a Ram 2500 with a short box and the Aluma Tray 8' fits a Ram 2500 with an 8 foot long box. Both are rated to 3,000 lbs evenly distributed and come with four locking under-deck storage boxes and a Rhino Lined deck.
Which Aluma Tray fits a Ram 3500?
It depends on the configuration. A Ram 3500 with a short box takes the Aluma Tray 6.75', a Ram 3500 with an 8 foot long box takes the Aluma Tray 8', and a Ram 3500 chassis cab with a 60 inch cab to axle measurement takes the Aluma Tray HD-60. The HD-60 is rated to 5,000 lbs and includes its 7 inch bulkhead.
How much does a flatbed for a Ram 2500 or 3500 cost?
Starting prices are $11,819 USD for the 6.75', $12,879 USD for the 8' and $17,820 USD for the HD-60. Every build also needs a tray to chassis mounting kit at $1,166 and a fuel kit priced by your engine, and the 6.75' and 8' need a front bulkhead starting at $3,329. All pricing is USD.
Do I need dually fenders on a Ram 3500?
Only if your Ram 3500 is a dual rear wheel truck. The dually fender extension kit is $2,268 USD and includes fenders, a stair mount extender and a set of jack extensions for the front jacks. It is available on the 8', HD-60 and HD-60-HC, and it is not offered on the 6.75'.
How long does an Aluma Tray take to build?
Typical lead time is about 8 weeks. Lead time moves with order volume, so check current build slots with us or with your dealer before you plan an install date.
Will an Aluma Tray fit my camper?
Most hard side slide-in and flatbed campers can run on an Aluma Tray, but fit depends on the camper, not just the truck. Talk to us or an authorized dealer with your camper make, model and dimensions before ordering.
Will a flatbed fit my Ram 2500 or 3500 short bed?
Yes. The Aluma Tray 6.75' fits the Ram 2500 and Ram 3500 short box. It is rated to 3,000 lbs evenly distributed and starts at $11,819 USD. It is a single rear wheel flatbed: the dually fender kit is not offered on the 6.75', so talk to us first if your short box truck is on dual rear wheels.
What happens to the fuel filler on a Ram 2500 or 3500 flatbed?
You fill at the bulkhead instead. Every Aluma Tray has the fuel and DEF fills built into the bulkhead, so you fill from above the deck. The fuel kit is a required item and it is priced by your engine: $290 gas, $290 diesel without DEF, $542 diesel with DEF.
Can I keep my hitch on a Ram 2500 or 3500 flatbed?
Yes. Your truck's factory hitch receiver stays the same and stays intact when the flatbed goes on. It only changes if you arrange something different with your dealer.
Does a regular cab or 4x4 Ram 3500 need a different flatbed?
No. Regular cab, crew cab or Mega Cab, 4x4 or 2WD, the flatbed is the same. The box length decides: the short box takes the Aluma Tray 6.75' and the 8 foot long box takes the Aluma Tray 8'.
Will an Aluma Tray fit a Ram Mega Cab?
Yes. The Mega Cab has a short box, so a Ram 2500 or 3500 Mega Cab takes the Aluma Tray 6.75'. It is rated to 3,000 lbs evenly distributed and starts at $11,819 USD. The dually fender kit is not offered on the 6.75', so talk to us before you order if your Mega Cab 3500 runs dual rear wheels.
