Need opinions on a new trailer.

[Skools Out]

i know everyone says Aluminum but they crack on highway trips from the flexing i've had 2 crack and seen several crack, you are better off with the steel trailer. I have 4 aluminum tandem trailers but the boats i plan on keeping i'm putting on Steel trailers. i'm taking the 250 Wellcraft off the aluminum trailer due to cracks on it and putting it on a steel one.

I have a tandem that was under my V20 i'm selling it has no brakes but it is a 6200# trailer all aluminum with new tires and lights.
