My sister had one. She actually lived in it while her husband was going thru chemo so she could be close to the hospital. She had it fixed up cute as a button, all open inside, with the bed in back and she modded it to have chairs and a bookshelf on the side where she kept her tv and misc nick nacky things.
On the OUTSIDE, it was constantly covered in a big blue tarp, there was tape on the windows
, and the floor mooshed when walking on it. Water was dripping inside the walls.
Hey, I told her NOT to buy it.. she wouldn't listen. During a particularly bad spell of rain that closed the hiway up here, I had hitched up the 13 and got out of dodge before I WASN'T allowed out of dodge. I somehow, by co-incidence, ended up at the rv park they were in. They were drowning, and they stayed in MY trailer to keep warm and dry. Real fun with two extra large adults, one with feeding tubes and stents, me.. and 3 very wet dogs! (They have a JRT)
That was my first pang for having a bathroom...
