I'm going to be honest here... the first thing that came to mind was... jumping castle! So follow up questions.. does deflating count as "dismantle"? And is said thing a giant jumping castle, because that would be awesome?

I feel like it checks a lot of the boxes:

• It is large ✓
• It will have to be dismantled ✓ (Maybe?)
• It is something that I was planning on getting one day anyway ✓ (Who doesn't?)
• It'll be perfect for my lifestyle, hobbies, and can help provide an income from home ✓ (I guess?)
• We are hoping that it'll fit in the dump trailer. ✓

On a more serious note, my experience of the community has also been great thus far, and it's always nice to see people supporting each other. Kudos to whomever is blessing you.
