Hi Pippi,
Im a techy guy and been persuing info on rv living and i love stewarding the environment and green clean living, getting off the grid etc.
i saw your videos and on one you mention always being cold if its cold outside or being hot if hot outside.
i was just going to make suggestion, there is some really cool tech out there called aerogel for insulation. it isolates heat yet is really thin and you can like, put a blow torch hon one side and crayons on the other and they wont melt.
heres the areogel website
also, if you dont know, look into home appliance atmosphereic water extraction; and distillers for water . for electric look at the xantrex power hub;solar inputs. they offer a 1800 watt unit.
and otherwise i bet you get this a lot yet you are such a hottie/angel.
have a nice day
