Stan, be careful of the advice you get from cheaprvliving.com. Not all of it is good.
I recently saw a question from an inexperienced person camping thruthe winter in a SUV on how to keep warm. Hundreds of people freeze to death in cars every winter and hundreds more end up in hospitals and losing body parts. Yet most of the advice given to this person was about sleeping bags and hot drinks. The fanatic stealthers were actively hostile to the idea of getting into a park or seeking electrical hookup for a heater for the colder months and tried to discourage the questioner from doing so. Their advice was both reckless and dangerous.
I would consider the source and think twice about anything I heard over there that may affect your health or survival.
