I have not seen a
Rocket Mass Heater for a Vehicle, I will just build one. The basics are there from Paul and others, I will need the following to make it right for a vehicle;
size
weight
type of mass that is light and conducts heat
determination to do this!
$$ Insurance,
right now I am with State Farm for all my insurance needs, my Camper costs $27.50 per month, as I pay monthly.
It is not my primary vehicle, my work vehicle is my primary vehicle, so I get a multi-vehicle and multi- product discount as I have Business Insurance as well
Vehicles that are converted or campers that people are getting rid off seem to start at about $300 and up, you need to be willing to work on them though or go straight to the $5000 ones that need no work.
Your other question is harder to
answer as I am lowering my costs monthly and just got offered a stay on the property and work on it in exchange for no rent.
As for actual $$ as in my bills, I do not discuss things like that on-line in a forum.
My goal on the other-hand is to pay as little for living expenses as possible, save up for a piece of property for myself and park my camper and work vehicle on it, build a Yurt or Winter Yurt and live comfortably never losing my house and land due to a Wife racking up Tens of Thousands in debt again, losing everything to the lender again!
