In this case it is because Mom said that I could, but couldn't build a shed-type building. Should I talk to her again because there is a high chance she would say something different?

I really do not want to pay $300 for a trailer that I will not actually use. I would rather just build on top of concrete blocks instead of putting down concrete blocks, assembling a $300 trailer on top of it, and then building.

Then again, if I just build a tiny office with trailer wheels and a coupler, the old lady across the fence calls the police on me because she doesn't like the new building, I tell them "Hey! It is a trailer!' and they say "No it's not," I could be in trouble.
