years ago, there was a small single garage about 12 miles away, I had a 24 foot flat bed, trailer, and I took that and a handy man jack and we got it started up and blocked it back the trailer under or in it, and bolted 2x6 across the walls and across the trailers bed, put one about every 4 foot, every thing was going great, about 15 to 20 mph and were two miles from home and came to a cross road and the crossing road was raised up some, when we went over the cross road the trailer went up and the building did not as fast, about 100 yards down the road I looked back at it and saw the back of it lower and then you could see each 2x6 break and then the building was skidding down the dirt road, and then made a quick left turn and flattened out across the road, I backed up got a chain out and pulled the pieces off on one side, of the road so people could get around it went home came back with the loader tractor, knocked some holes in one of the walls to chain up to, and layed the other wall and roof sections on the wall section I had chained to the tractor and drug it in the ditch the rest of the way home and straight in to the burn pit,
I will say I have had better days, but do wish I had a video of the unloading of the building,
If I would have use a 2x6 on every stud section would have been fine or doubled them up, probably 2x8's would have been better,
live and learn, but I have seen buildings skidded short distances, and
Part of the problem on this building was there were doors on both ends and a very unstable building in the first place, the way I remember it was about 12' wide maybe a little wider possibly 14 foot,
