Ask HN: Hacker in the Trailer

Ok so first sorry for this "Real Estate" offtopic here.

I am going to work on something in Valley for about a year and thinking about buying a trailer and living in a park. Yes, I always dreamed about such experience. Yes, I am looking to sell it after i finish that project and understand that i will probably loose some money on that deal.

So, can anyone suggest a good resource or personal advices on buying trailer, good parks, Internet access, things to know, etc.

I dont have strict location preferences yet- anywhere between SF and San Jose is fine. I have a car and will be working from home most of the time.

Maybe there are other hackers here who dreamed about living in trailer/hate renting small room in noisy SF with emergency cars passing by every minute/want to spend more time on air/love barbecue?
