HMMM
All Part of a Evil Idea I've had for moons.
1 Remove Fridge put in shelves Cap Gas lines (done)
2 install dual battery set up with maintainer so when you plug into
power it charges and maintains both (started, Not done)
3 add electrical outlets ( 1 by back hatch cabinet 1 by sliding door
) interior lighting with switch by sliding door. (done)
4 add propane heat and Hot water tank or Instant Hot water, using
capped fridge gas lines, Vented through Flue Vent. ( still on the
drawing board )

Presently for water we use a coleman hot water gig that uses the
Propane bottles. Instant hot water, great gig, Wife likes it, so I like it.
Heat is Electric for 110V plug in with T-stat. during the day it is a
little buddy in the tent. Same small propane bottles.
Still not 100% sure how I want it to finish it out. Soon Very Soon.
