We put it in the camper world in Eugene OR and found out that it had front structural damage where they tore out all the the foam off the front goose neck & replaced it with tongue in groove wood. In November 2021 we were finally able to bring the trailer back to Utah. On our way home. We blew two driver side tires simultaneously. It caused thousands to repair. …”
