The storage unit (or Aladdin's cave).

Bob has a storage unit, unlike many storage units his does not contain common junk, his contains his obsession.

He has had several storage units in the past in the different places he has lived, and they have cost him more than the stuff in them is currently worth. He once stored a fire truck for 10+ years at a cost of $230 per month. He bought the fire truck for $1000, put $9000 in to fixing it up, and stored it at cost of about $27600, when he moved I had to sell it, and only got $2000 for it.

His current storage unit holds several hundred pieces of MTH trains and rolling stock, some Lionel, and misc or railroad related items, like books, etc.

He also stores a large amount of die-cast metal firetrucks and other vehicles. Many of which (as he puts it) "are hard to find anymore!". They are hard to find because I know a grumpy old guy who's hoarding them in his storage unit.

To give you an idea of the stuff he used to have before he moved, here is the old storage unit:

And the fire truck he kept in there as well.

Yes it all fit in there "like a glove".
