I'm eyeing getting pic related as it's within my budget and size specs. I have a 1 bedroom apartment but am looking to save money. Is this a good idea? Only in the planning stages right now but I live alone and can get a gym membership for the shower/parking but could install a shower in the box as well I've just never done it before.

Been watching videos like this, tell me this isn't completely retarded. Biggest considerations would be of course stealth and avoiding being bothered by the police. I also enjoy having my own washer and dryer too much.
