I went from a 1963
AS Tradewind to a 1999 Trailmanor 3023 then to a 1979 Argosy (my current camper).
The Tradewind was spending about as much time in the repair shop as it was in the campground. After spending three days of an all-to-rare one week camping trip in an RV repair shop we decided to sell. We bought a trailmanor based on their supposed ability to be towed by an SUV and slick advertising images.
The trailmanor's folding mechanism works over pressed fiberboard, vinyl and plastic held together with metal screws that can loosen and fall out. The vinyl cushioning of the upper part would scratch the interior pressboard walls as the unit opened and closed. However, the trailmanor company is great. I recall ordering the broken plastic bits at a very reasonable cost. However, we found that the trailmanor was not economical to tow and the breaking pressboard/plastic bits left us with a feeling of owning something cheaply made. One plus for the trailmanor over other "popups" is the axle is set closer to the rear of the trailer making for easy towing. I've wondered why other campers (including Airstreams) haven't done this, but then again I'm not an engineer.
Trailmanor's have good resale value. We sold ours for more than we paid for it. However, we were happy to be back in an Airstream. Our Airstreams have required attention and repair, but when the day is done we have product that is well-built and still economical to use. We just want to camp and maximize our fun while camping as much as we can afford to do so.
