Bought a 2019 Imagine brand new, a 2600 RB, weigh around 7000 lbs dry. First long trip, springs gave out, went flat, Grand Design replaced those under warranty, next was the rear axle bent. Turns out,...
Repaired, bent between the spring mount and the backing plate for the brakes, a distance of about six inches. Done by a shop that builds trailers commercially, his best guess was a bad hit from a pothole or frost heave, he's seen it before. Incidentally, he had three more new travel trailers behind mine, to replace bent axles, and that was just today, says he does a lot of replacements on travel trailers. Regardless of the manufacturer, they're not built heavy enough anymore.
