I have kind of wondered the same thing.
Where my parents live the power has gone out in winter for an extended period of time once every other year. For the most part it isn't a problem, BUT there is always the concern for water pipes freezing. What would it take to hook up their GMC Yukon to the Gas furnace in the house? I assume if they heat up the house once a day or once every other day the pipes will not freeze.
Assuming I get a truck camper and decide to camp not in a camping ground, what would you recommend for an inverter and what could I power? Can I run the AC in the truck camper? Can I run the microwave? I do not have a truck camper at this time, so this is just part of the deep research for the plan.
One day, I shall come back. Yes, I shall come back. Until then, there must be no regrets, no tears, no anxieties. Just go forward in all your beliefs and prove to me that I am not mistaken in mine.
