I don’t think mine can ever be moved. It has been sitting here since 1968, has an addition and a wrap-around deck. LOL!
(But the hitch is still attached)
We had an addition we added at the back door for storage of tools, etc. Also had skirting. Sold it after we moved into the house. They eventually moved and took it with them.
At only 10 ft. wide, it’s not that bad to move. It was the last 10 wide on the lot- the new models were all 12 ft. wide, cost more, and because of the layout, had smaller bedrooms.
