With respect to furnishings, you can buy cheap or you can buy durable, from same manufacturer and often in pretty much the same shell. That's part of why most have multiple model lines. You have to apply same criteria you would in shopping furniture, or buying kitchen cabinets, judging where you want to be on cost vs quality spectrum.
Some manufacturers start at a higher level than others, lowest line is not cheap. In fivers, without getting into the real premium brands, Hitchhiker and Carriage come to mind, for the market in this part of the country. Many older examples in use 10-20 years. Other places, might be other brands.
If you are looking to spot it and live in it for a couple years, be wary of the description "ultralite" or "superlite" because they get weight down by paring dimensions of as many materials as they can. I think that will impact long term durability.
