The question I have is, would the existing TC market be willing to pay 1.5 to 2 times as much for a better built unit? My assessment of the situation is, no, by and large they would not.
Better built campers have come and gone. Gonna come in and set the industry on its ear. What happened? "Too expensive."
Until the buying market is willing to put its money where its mouth is, and more of it, you will continue to get more of the same.
