I simply put the bottles on the tongue, run a propane line and put in a deep cycle battery for the rig. I can run it on one bottle all week, but I have to charge the battery every couple of days.
It's not hot enough to dry cloths out, but it's plenty warn for sleeping. I insulated the trailer with that pink foam too - the only thing that isn't insulated is the floor, I used foam to insulate the back doors (hard to take those pannels off).
