I’d judge this to be from the 1990’s. It’s a very fun and funny history of trailers (some mention of manufactured houses and tiny homes, but Trailers). Partial-color photograph on front shows an elderly woman planting flowers in her repurposed commode, no a flowerpot, in front of her trailer. The epilogue is, for a reason I’ve forgotten, the story of someone who watched a wolf take a piece of wool between his teeth and back slowly into a lack and submerge himself; the observer figuring the wolf knew his fleas would move to the ball of fuzz (I think lanolin was mentioned).
It is quite a read. The public library has no memory of it, even in records. Online there is nothing at all resembling it. Please help!
