swap dually pickup bed for alum flat bed

As the title states. I am considering swapping my dually pick up bed for a aluminum flat bed. Mine is a 2000 F350 and his is a 2000 F550. Will this swap work? what all will need to be done? I know on the old body style the cab and chassis frames were narrower and a pickup bed had to have the bed mounting holes drilled on a narrower pattern. any help would be appreciated

You already know half of it. The rails on the 550 are wider, but they are also flat. Your 350 has the narrower rails, and they are NOT flat. So to mount the flat bed on your truck, you will need to offset the mounting surfaces to match. The biggest issue will be dealing with the rails being different widths. Depending on how the bed was made, will make it easy, or hard.

Mounting yoru bed, on his truck will be harder. The flat rails on his truck means the varying heights of mounting rails will have to be changed. Again, the mounting bolt locations will also have to be redrilled.

The biggest difference, is going to be in the length of the framerails. My bet is that the rails on his 550 are longer, which means they are going to stick out past the end of your bed. Easy for you to work around, a lot harder for him. There are a few people on here that have done it. Hopefully they will chime in.

I'm curious, do the support rails on the flat bed run front to back or side to side?

Putting a pickup bed on a chassis cab truck is a major project. It's been done, and often, but the pros charge about $5,000 to do the deed.

Putting the flatbed from a chassis cab onto a pickup is also a major PITA. It requires lots of fabrication of connecting parts.

You'd be better off to look for a flatbed that's designed to be installed on your truck. The flatbed/platform body builders make those for pickups, and they are different than the ones they make for chassis cabs. Maybe do the trade with your current contact, then trade the resulting flatbed to your local truck body outfit for a different flatbed that's designed to be installed on a pickup. Look in the yellow pages under "truck bodies".

My Sierra Blanca in the sig pic was a great pickup for 11.5 years. I sold it a coupla years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream.
