I moved up this year too:
FEMA Trailer $3k delivered, AC, and heat controlled by a nice thermostat.
Hot water for shower and washing up.
The well had not been used in my life time well, but after a new pump house, she pumps 2+gal/min.
The john runs 10' to a 70gal septic tank and then a 10' leach line.
Storage trailer
