My wife and I live full time (typically, or rent depending where we are) in a 2013 42’ fifth wheel. For reference, msrp was like $83k and we paid $56k. Things break a lot. We’ve replace both AC’s, amongst lots of other repairs. You get pretty handy, especially when you full time and can’t eeally bring your “home” in to be dropped off for a month.
It’s a good lifestyle that fits my work as we move all over the country 1-2x a year. We may end up downsizing size wise, but upgrading quality wise, into something like an airstream and then get an enclosed trailer for our belongings (bikes, tools, clothes, etc.) most trailers are incredibly cheaply built to be, well, cheap. But also to be light weight and easier to tow. The incredibly cheap EVERYTHING gets a bit old when it’s your permanent residence. Often, you get what you pay for.
