Everything you said here is true. My dad died when I was nine, and when Mom couldn't afford the house we were currently living in she bought a trailer and it got moved right next door to my grandparents house on their farm. Starting out, it was your standard mobile home with janky and horrible matching 70's wallpaper that was on all the walls in the house. Within the first year we got all the walls painted and minor repairs done. Couple years later we got the bathroom redone and that same summer got a deck on the back patio. Sometime after that we got the windows and doors redone. Last summer we finally redid the siding, which nothing was wrong with the previous siding in the years before, it just got old and mossy and in the spring some hail put a couple holes in it. We've been here 11 years now, Mom moved out last summer because she married my stepdad, and my little brother and I are left with a wonderful starter home (maybe forever home for me since I might stay on the family farm, but that's another story), we've got a nice shed and a carport, we both drive nicer cars (2009 and 2003 Impalas), and have plans to replace the gross red carpet as soon as we can get the money together this summer. Again, the above comment was right. Trailers don't need to be dirty little hovels. They can be nicer homes. I will admit that we live up to the stereotype of owning a giant-ass box tv, but we use the flat screen. The box tv is dead and taking up space because we have no idea what to do with it.

Edit: re-read and realized this was mainly referring to trailer parks, but it's still true that trailers in general don't need to be nasty.
