Portable Shed / Cabin - Lift stress points

[cbc58]

I am toying around with the idea of building a 6x12 shed that goes on the back of a 6x12 open trailer that can be used for camping/ temp housing and/or storage.  I want to build it so that it can be lifted off and onto a trailer and am wondering how to construct it so that it stays together when lifted. 

Right now I envision big eye hooks on each end where a cable can attach so it can be lifted while the trailer is moved out from underneath.  This way I can use it when needed and also have the trailer for other jobs/work.

How would the framing need to be constructed so that the thing doesn't break apart when being lifted?  Would a cable need to be run inside the wall of each end to make this work?  Any other ideas of getting it on/off a trailer?  Thought about rolling it on/off or possibly skids with winch / come-a-long.

I think it would be easier to build it so you could just attach an axle when needed. Housemovers use portable axles all the time. 

If you really want to lift it, your idea sounds about right.

As for the skids, there is a portable builder in Albuquerque (Allstate) who does just that.  He runs the skids perpendicular to the floor joists.  They are the next larger dimensional lumber size up from the joists.  If you use 2x8 for the joists, use 2x10 for the skids.  Notched angle at both ends. Joist hangers off the skids on both sides.  He puts a double joist up front, and pulls them right up onto a tow truck.

Just thinking ahead, don't forget about height restrictions if you plan to tow it. The builder in NM builds different styles, but his flat-roofed adobe style is much shorter than a pitched roof.  You can get to 13' in a hurry.

I think I would rather jack it up a more normalish structure on skids and blocks with hi-lift jacks and drive a trailer under it then let it back down than try to crane lift it into a trailer.

I would look into pickup camper jacks.

tks for the replies.  thinking skids and jacks is a better idea now.

skids with two slots to slide beams under to jack.
