I have a 9' x 102" flatbed on my truck, and I absolutely love it!
I use it for work as well, but when it comes to toys (when I have time for) it's super!

I have a cpl of 165" sleds, and my chum has a cpl of 174's. If we hook a trailer on behind, things git a bit escalated.
We end up throwing the back end of the sleds way out to the full 102" so that we can pull into a gas pump or whatnot.
That is with a drive-out V front.

It's not bad as long as you don't forget about the trailer back there.

A 174" sled is prolly about as long as you are talking. So - what is your plan for the hitch?
Extending the hitch on the truck? Or are you thinking that you would never want to have the deck and the trailer at the same time?

I did have a deck built that was prolly 10' long? I could git 3 ATV's on it anyhow...

This is the best pic that I have scanned for the side view of that deck. Not a very good for the app, but I was hoping to show what 10' deck looks like. It wasn't bad at all, but 12' sure sounds like a doozie.

But I could squeez 3 ATV's on my 9' bed tho too, but barely:

Now here is an idea that I have in my pocket, not exactly expecting to employ it, but in the case as you say - you could doo it if you needed to sometime ....

My ramps slide into my bed like you see here. Shown with one partially slid out, and the other'n is all comfy in it's rack.
Now - if you had a cpl'a chums, and ass_u_ming that you would have if you are wanting to add the third sled ... then two guys could lift the sled up, and then the ramps could be slid almost into place, and let the skis just set right on the partially extended ramps.

Only catch with this is that the ramps will want to move going down the road (normally moving fwd, but in this case it could be out?) so a fella would want some kind'a shot pin to keep them where they are.

[edit]
There is a chance that I used this trick 20 yrs ago when we took 3 sleds when I had both kids along. But one of the sleds was an old Yammi 300 that didn't take up a lot of real-estate. So, maybe we did that, and maybe we didn't? I don't remember anymore.
[/edit]

Having the full 12' deck likely wouldn't make that a whole lot easier? Getting that third sled up the ramp isn't likely going to be a one-man job anyway. (???)

My newer truck has same design bed, but this time out of stainless!

I have a goose ball in them as well.

I REALLY like the flatbed over the deck tho! The load is lower, and feels MUCH lower! On the flatbed it is not even felt, but even with training wheels, you know that deck is up there. And on icy roads, I like low!

Could I interest you in building a bed in stead?

Looks good -
A flat bed is a no go on my end. I do have a 3000lb 9' floor length slide in camper as well so I understand the top heavy weight and how things get affected. I will need to layout the sleds on my floor to see what the minimum size needs to be. Maybe a 10.5-11' version will work...

 

Or, maybe it's time to upgrade to a 5th wheel (gooseneck?) camper?

Well, you could employ the extended ramp idea on a deck as well.

Ya, maybe. I would need to figure out a way to allow a center slideout mate with a ramp.

 

Not sure what your state regulations may be but you might want to check overhang regs first with them. Here in BC our revenures were requiring lights on anything that extended past the bumper 18" or more?

 

If you doo a 12' deck, please post pics and update us how it went.
I'm not doubting the trucks ability - as it's not really all that much weight, although it is way out the back.
And with a crew cab - it shouldn't make the front light much either.
But I still like to load ahead of the axle if possible.

3 or more sleds just hook up a trailer and enjoy no salt spray. I wouldn't want that much weight that high. F350 or not. 1500 lbs of sleds and 500 lbs of deck is a lot of weight to be that high on any turn or uneven ground.

I know two guys that sold their sled decks. The height and not being enclosed was an issue.

If I really wanted to I would take the bed off an make a flatbed maybe a removeable or flip up tailgate you could put the third sled on.. then build a special mount for the camper. The lower height is much more manageable.

If you only take a couple trips a year just deal with the enclosed trailer. Plan ahead so you RZR/Mav UTV fits in it.

I have a neighbor that has a dbl deck - deck.
2 sleds over the cab, and 2 over the back - like normal.

On a SRW truck!

He ran this rig for many years, and much of that time they were typically in the UP one weekend, and Rabbit Ears the next. He hasn't been riding in several years now, but I'm sure there are folks on here that can remember seeing his truck. They put 10's of thousands of miles on that set-up.

Not for me....
