What kind of barn is it? I have a pole barn that was built over a 56' mobile home... it had been there a long time. I had to reduce it to a deck. I opened the end of the barn (thankfully no poles in the way), fixed the tires, got it outside, turned it around between the trees & pulled it 500 feet out to the street with my backhoe. My junk guy said he'd take it if I did... what a thrill that was. We ran interferance on the road... to the junk yard.
He needed all of the 2 lane country road & we had to physically block idiots trying to pass him... & he wasn't going that slow, down hill with only the brakes on his one ton truck.
I used to work in a ship yard... it was every day paractice to move 40 foot aux sail boats in cradles on planks & rollers. Rollers were about 3 feet long & the diameter of a baseball bat. The old Swede used to "tune" the rollers with a sledge as we stayed clear of the cable through a block on a dead man. We could also do this equally well on gravel or on a concret floor... though indoors we could lift the cradles with automotive floor jacks & move them that way.
