Need pics of the base and floor.
Is it one of those they drop off, or is it built right on the ground or a pad?
The reason I ask is, we rented a house in town, I thought we were going to be there long term.
So I bought one of those nice already built sheds they just drop off and level.
Then a year later, we bought a bigger nicer place outside of town and I was not about to let my new shed go to the landlord....
I got a hold of a similar place that I bought mine from and just asked them If I pay them, would they pick it up from address at Point A and Drop it off at Point B.
The guy quoted me 200 to move it.
I took everything out and fully unloaded it. It looked just like it did when dropped off, originally.
He was able to back right up to it, load it, and pull off. At the drop off, it was the exact reverse of that, no issues.
It was so easy, he told me he'd just change me 150 vs the 200. I gave him the other 50 as a tip because I was so happy to have the shed at my new place and not have too leave it at the old place.
So, that MAY be something you can try. The right tools and Rig really make the job. The wrong, could make kindling...
