ahhahahah that igloo thing reminded me of this
a small island I lived on a guy who lived out of a old ice cream truck

and used marbles he shaved down to replace his teeth

to say he was a character was a understatement
he had this old beater car and had rigged a washing setup on the back that his exhaust went through to help heat the water

and he would drive around to wash his clothes
the front hood he had this screen covered the whole hood on that opened up and would close down with another screen over the top when done washing he would lay his clothes out and drive around to dry them
somehow the idea that putting the clean clothes on the hood on dirty roads was not really doing the job but then again he had marbles for teeth

I kinda wonder if he had done his own brain surgery
I wish I had pics

but was quite unique
the ice cream truck was insulated though

the one compartment that was long width of the rig was his sleeping are the other parts he had to hold his possessions
but the truck had not moved in like maybe 20 years so was just a shell basically
