So I replaced one of the batteries & the alternator and the truck worked well all week until this afternoon. The guys were on their way back to the shop & the battery light started flashing. Is the 110 Amp alternator not enough (that's what was in the truck to begin with) or is the battery I didn't replace shot or both? What alternator do you recommend for an '06 F450 landscape dump w/ 6.0L diesel single alternator set-up? I'll order on-line as soon as I hear from y'all I guess...

Get a new battery to match it's friend. Replace in pairs as has been said many times above.
It's not. I have two dead 110A and a dead 140A to back that up.
Call this guy and tell him your troubles. He'll sell you the correct part, and also make sure you haven't nuked the FICM during all this.

I bought this alternator:
270 Amp XP Series Alternator for 6.0L
This is a good upgrade over stock if you don't want to go big:
185 Amp Series Alternator for 6.0L
This is the Leece Neville unit everyone loves lately, but make sure you order the pulley with it because it's a minor PITA to install (you need a pass through socket):
Leece Neville 230 amp alternator
If you do the underdrive pulley there's a slight chance you need a new belt tensioner depending on how slack yours is with the smaller pulley.
Honestly, THIS IS THE ALTERNATOR that you actually need.
Advance Auto sells a 140A unit, you can use the code TRT30 to save 30% on it if you buy online and ship it to your local store. I don't think 140A is enough though, I have a dead one on the shelf to support this opinion. Plus make sure you check all the cables, and add the ground cables I linked to in post #12. I did the complete cable set from FICMrepair, but there is an argument to if it's necessary or not even with a larger alternator.... the extra ground cables are pretty well unarguable based on the hard data Jack provided.

The OEM alts are reported to produce approximately 50% of what they are rated at. This means your new 110a alt is producing a max of around 55-60 amps. This is not near enough for a diesel super duty - especially one with a dump bed.

I would highly recommend getting the Leece-Neville 230a for your application, a very good price is from XDP with its Diesel10 discount is a good choice from a reputable seller.
With it you will need to increase the alternator to battery cable with a 2ga wire and fuse, and with the dump body I would install improved cables on the battery cross and driver's side negative side, adding a cable between the frame and motor. That cable is even recommended in Ford's Body Builders Guide. That all that necessary as other cables are not necessary.
I use a dump trailer on the farm with quick cycling and we had an F-550 dump at the test facility, I know your situation well.
