We made this same expensive mistake. Settled on trailer that was 1/2 ton towable, then 9 months later bought a 3/4 ton, so of course we then sold the first trailer and bought the one we wanted.
We off set some of the loss by selling private party and spend the necessary time to find the trailer we actually wanted as a private party used purchase.
We are a family of 5 a very happy with our 29QBH.
