Wow- what a view this one must have- once you've changed your underwear from the climb up! I have to imagine that this camper/tv/teardrop trailer swings pretty severely in the wind, but just the fact that anyone attempted to do this (assuming its not a hacked/altered photo) is pretty darn gutsy- or perhaps just plain stupid.
On a more serious note, I've said it many times before, but for the the budget-minded (or those broke), there are few simpler or affordable ways to find/acquire decent shelter or tiny/small house than to buy an old camper and rehab the inside. My own neighbor was selling one for a mere $500 a little ways back- 22' feet long. As long as you're in a warm season (or in a year-round temperate climate) and the roof is rain tight, you can then set upon refinishing the inside as time and money allow.
