Whomever wrote this article is really misled. First, a small house is a small house and whether it has wheels on it or not is really irrelevant. Actually, many newer park-model trailers are every bit as nice and materials as "upscale" as a stick-built home. This article came across as very snobby to me, because the topic of interest here is enjoying and relishing small spaces and examining how others have done it so we can hopefully do it one day; not in debating that a trailer has less expensive parts. I think whomever wrote this article misstated many facts. I hope most folks will continue "the cause" and explore small spaces OF ALL KINDS – including those with wheels on them. Think small and be small and don't be led astray by writers like this one that are apparently hung-up on stereotypes.
