I think you would be lucky to move the buildings without taking them apart. But on the flip side, I wouldn't want to take them apart either - they are horrible to put together the first time. Ask someone who moves houses.

GO to U haul and rent flat bed trailer ( cost about $25.00 plus beer) Take everything out of the sheds. Invite all your friends over for shed moving party. tell them the beer is 12 miles away and we need to take the sheds with us to get the beer works every time CAUTION! never drink and drive at shed moving parties

take a couple of 4x4 and place under the shed long ways of the building

anchor the floor to the 4x4 with lag bolts

than you can take a cable host and host the building onto a trailer

you are just putting skids under the shed

it will help if you take 2or 3 2 inch pipes and let the 4x4's 'roll' on the pipes placing the one from behind and moving it up to the front as you winch it
