Brings back a memory of when I lived in Pennsylvania. At the time, I was living in a rented single wide trailer, not much of one, that sat on an acre or so of ground. Being renters, we didn't do a whole lot but did end up putting a nice covered porch / deck on the front of it. They paid for the materials. It was a nice spot. Amish school house was behind us, woods on two of the other sides. Room for a garden and a few chickens. Coulda been a whole lot worse.
But there was a guy next door to us that was a carpenter. He started out with an older single wide trailer as well. Since he owned his property, I believe he pretty much just started doing "little things" with a big objective. Over time, that old single wide trailer became a stick built house that was a little over twice the size of the original single wide. He showed us the inside of it one time and a person wouldn't have ever known it's beginnings. I asked whether there was anything left of the old trailer. His answer; "only the steel framework that was underneath". And apparently the county still thought it was a "trailer" and taxed it accordingly. Probably couldn't get away with that today, all the regulations and such, but a few skills and some persistence can get a person way more than most would imagine.
Just sharin' a flashback from memory lane.
