Need to move a 15x20 shed. How would GRM do it?

I have a neighbor that's looking to get rid of an old tin shed that's on his place. It's about 15' x 20' and we would have to move it 1.5 miles down a gravel road to our place. I have access to two loader tractors as well as deck over flatbed. Right now I'm thinking a guy could just get a tractor on each side and slowly lift it up and then back the trailer up underneath it. Assuming that this isnt a terrible idea, What would be the best way to brace the building for something like this? It has a solid floor that isn't really supported right now. Then I figured we would want to brace the inside as well. 

Thoughts? Do you guys have any better ideas?

There are 'forklifts' specifically for this. I think they are called Mules. Also there are wheels that you use with the mule to roll the sheds around. 

I'd think that a consultation with someone who runs a Mule for a living would be well worth the money before you do anything. 

The last one I moved was jacked up with a farm jack, a flat deck trailer backed under it, moved and set back down with the same jack. Total time about 4 hours. 

I know you said gravel road... private road?  I only mention it because getting nabbed for transporting an oversized load without permits is scaled based on the types of permits which would be required.  You'll be over weight, over height, and waaaaaay over width.

Hate to sound like a mother telling you to wear clean underwear, but in PA that would be (estimating) about $807 for weight plus a 20-cent per pound overweight surcharge, $300 per width class exceeded (up to 10', 10-12.5', 12.5-13.5', 13.5-14.5', over 14.5' is only by special exception, only transportable during the middle of the day on weekends, requires two escorts, etc)  which would be $1500 + 600 for no escort.  Overheight (more than 13.5') $500.

I'm just saying.... if you're confident that no one will care, go for it.  I have total faith in YOU, just be aware that in PA that could very easily become a $4000 trip.

My only real concern about the shed is that (even with a full 8' width trailer) you will have nearly 4' unsupported hanging over the edge.  A nice new shed probably wouldn't even creak, but an older shed could just crumble.  Looks like corrugated steel siding?  That offers next to zero rigidity unless there is OSB or other sheathing behind it.  Shiplap or T&G siding won't help much either.  Any option for maybe a few 16' glu-lams across the bed?  Maybe a dozen 2x6-16's?  Do the floor joists run along the 15' dimension, or the 20' way?

Hire 50 Amish men to pick it up and carry it 1.5 miles down the road.

It's not a private road, but we really only have a couple cars a day go by, one of which is the mail truck. I think South Dakota may be a bit more lenient. I did a quick look through and couldn't find any width restrictions, especially if it's ag related. And I don't believe it would exceed the height and possibly the weight restrictions. Though I could be totally wrong. I need to do some closer looking into this for sure.

I didn't get a super great look at the siding, it may be shiplap, but they're boards running vertical and then the tin is screwed onto those. The floor joists are run the 15' dimension. 

I kind of figured running some 2x6s across the trailer and setting it on there too.

I ran 4 - 12' 4x4s to support the width and keep from straining the floor. It was a 12 × 16 with a 12' peak. We moved mine about 15 miles early on a Sunday morning to avoid traffic. 

Former Mule operator here. Check with your local "No Credit Check" mini-barn lot if you have one. We used to charge $150ish fir this sort of thing. 

If unavailable, or prohibitive in price, as mentioned, long 4X4s under the floor to make skids, or sled runners of a sort.

Solid advice in PA, no laws apply here.

Well I called around. The local shed place said that it's too large for them, and the other quoted $6,000 to move it. However I ran my plan by him and he said that it sounded pretty good. So, I guess we'll see how it ends up going.

I can imagine a gravel road in SD being different than PA :)  I suppose if you had any trepidations, just tow it with the tractor instead of a truck.

Carry on, be safe, and send us photos.
