Anyone know of a source for them in Mississippi?

I know where there's a pretty pink one in a scenic swamp.  Don't think its for sale though.  Even it is, it would cost you your soul. And a large chunk of your GI tract.  All of your dignity. You might even die.

I see those things occasionally for sale but don't know of an actual store. Usually its at a place that sells barns or steel buildings.

This, Lowe's had plans for sale also. You may be better off building one instead of buying used, the materials would be better and you know there was nobody trashing it out as a meth lab "unless the place is selling new"

That one is sacred by this point, so there is no way it's leaving

The purpose is to have a small mobile house to live in while we build our house in the country, when we're done we'll move it another part of the farm and use it as a hunting cabin.

These seem to hold their value better than a trailer.

This is what I am doing.   Got a 1 bedroom one in 2010 to live in while we saved to build our house.   Moved in a few years back, and ought to be starting on the house any day now.   They actually look to have increased in value since I bought mine, so I OUGHT to break even fairly easily.    It's Really been a VERY good home.   Solid, well made, efficient, Quiet, etc.  The fixtures, and such were low quality, BUT those are easily replaced if they break or you get tired of looking at them. I ought to be done with mine by the end of the year if you're in the market still.  

I saw a big lot of them from 49 between Collins and Hattiesburg a few months ago.  Don't remember the name of the lot, but I'll try to remember to look when I go back down in a few weeks.
