Twenty feet wide sounds like a trailer house, I know, which we’d also lived in, but the difference in a trailer house and modular one, it’s that a modular house, it gets delivered and it stays there, more or less, while a trailer house keeps its wheels and the tongue it gets pulled with, so it can still roam if need be. They’ve both got skirts that never last the winter, though, and the sidings are pretty much the same, and if you end up with one of each, you can kind of rub them together like puffy Cheetos and make a bigger, more complicated house.
